While these people are extremely uninformed and their "solutions" would be absolutely catastrophic, they do have a point.
What they're noticing are the effects of corporatism: monopolies and other bad market practices caused by government regulation/meddling, often as a result of lobbying.
I'm talking about chemical patents and "safety regulations" making it practically impossible to compete with big pharma, making medicine extremely overpriced. Or government bailouts of banks which are long beyond bankruptcy causing all sorts of mishaps.
The only solution is a return to true capitalism. Career-politicians are just as guilty as (if not more than) the big corporations.
