The net margin of around 1.5% seems more relevant: the gross margin is just the revenue minus the cost of good sold plus cost of transportation. The net margin is the money you have left after paying things like Rent, employee wages, electricity, taxes, interest on debt.

as the time period gets longer, the the more likely it is that the numbers represent the true performance of the business rather than randomness. That has to be balanced against the fact that investors get less frequent updates i.e. the information is now potentially 6 months out of date rather than 3 months at worst. But then its just a judgment call of the relative benefit of each - you could argue that with modern accounting systems, modern companies could deliver weekly or even daily earnings , which would give investors much more timely information, and the high frequency would probably mean it wouldn’t be worth making the effort for management to fudge the numbers to bring forward or delay revenue one day or one week. There would be a lot more variance in the numbers if they were daily, but thats a good thing - it would just reflect the underlying randomness, and then the investors could decide when the accumulated trend over a period of time is meaningful or not, instead of management wasting time massaging numbers into a fairy tale of steady growth.

and you’re claiming the process still isn’t complete more than 40 years later? shouldn't the wealth gap between the poor in the US vs the poor in Afghanistan be starting to get smaller if your argument is correct?

why is returning the cart intrinsically some sign of “goodness” but returning your plates to the kitchen and washing them at a restaurant is not? The customer is at the store to fulfill their needs, not the store’s. Taking the groceries from the checkout to the car in a cart helps fulfill the customer’s aims. Returning the cart does not, same as picking up trash in the store car park does not. And the revenue from customers pays for return of the carts from the parking lot, so most customers feel that is a better deal than a place that forces them to return the carts.

The original article and many of the comments have a hugely moralistic tone - where are people expected to learn these implicit rules? If the store doesn’t care enough to communicate these expectations (assuming they even have them, and that they don’t only exist in the minds of the self-appointed “cart police”), why should customers follow them?

fyi, the account confirmation email redirects and ends up on a tab with address localhost:3000. looks like it did work, i was able to login after that, but many users may assume it failed and give up

could you maybe respond to the point made in the comment you are replying to? If it’s a good idea for all those other countries, why does the idea become a “turd” when america does it? is this some kind of “manifest destiny” (to be dumber than other countries)???

if it would give domestic manufacturers such great pricing power, then wouldn’t it also encourage foreign manufacturers to manufacture in the US to take advantage of that pricing power? Wouldn’t that be a good thing for the US? and as more manufacturers move to the US, wouldn’t that competition then tend to lower prices?

I wouldn’t classify this as binary thinking - isnt the comment you are replying just defining boundary conditions? Then those two points don’t define the entire space, but the output there does at least let us infer (but not prove) something about the nature of the “function” between those two points? Where the function f is something like f: experience -> productivity increase?

i’m assuming this is a system that changes the numbers in the question each time? often there is a separate “practice” button where you can practice and (maybe) get feedback, figure out the process, and then do the questions?

even if not, try putting the textbook and the question into an AI (I use the paid version of gemini, the $20/ month is the best money you’ll ever spend at college), then as it to explain how to answer the question. Then ask it to generate a similar question, and then give you feedback to you as you try to answer it. Then try and answer it step by step, repeat as many times as you like until you understand and keep getting the right answer, then answer the actual homework question.Feel free to dm me if you want to discuss!

The $200 million in north carolina is a discount on future taxes for when they start production. - seems a little unfair to count it against the company when they haven't even started production yet.

And the total amount of private funding raised to date is $700 million - so maybe 10% of funding to date is from the government? Seems like a good deal for the government?

so was the dam-busters raid by england in ww2 against nazi germany also “genocide”? or were they both just “warfare”

as the events of Rwanda showed, it doesn’t take very long for a nation state to successfully complete genocide. So are the israelis really incompetent at genocide, to the point where they drop leaflets that say when they’re going to bomb a building and call cell phones in the area to tell the civilian population to get out? or is this just the usual propaganda and hyperbole?

You’re assuming the price goes up as you approach, but it could equally go down - the whole point of “coupons” is to charge people more if they value time higher than money, and lower prices to those who value money more than time (usually lower income people). All other things being equal, a store would like more money, but raising prices reduces amount sold after the store already bought it and paid for it to be displayed, increasing the chance it is eventually wasted. You might find that stores regularly lower prices significantly towards the end of the day, or just for poorer customers, in order to reduce wastage. For those calling for regulation, the assumption is always that our analysis is so complete and obviously correct that regulation is justified - is there a reason we couldn’t actually wait and see if there are problems before trying to “solve” them?

Sure, except Moses and the Jewish people were on the land around 1500 BC, and the Islamic religion didn't start until after 500 CE. So the Jewish people got there at least 2000 years earlier, so if we are doing the "who ethnically cleansed who" game, I think the Jewish people appear to be at most, reversing the previous ethnic cleansing? Or is there some kind of moral "expiry date" on ethnic cleansing?
