As a married male software engineer in his 20s: the problem here is you. Your expectations are ridiculous and if you continue to seek a woman who meets them you will likely die alone.
You want an Indian woman living in the PNW, roughly your age (I assume) yet without any relationship experience, limited alcohol consumption and didn't party in her 20s?
I'm sure many people here would like a rich supermodel scientist who can cook a beautiful meal too. Would you say their inability to marry one is because of some change in society?
Drop your insane criteria entirely. You need to be meeting as many people as you can and _really_ getting to know them. For all you know, your perfect wife is a fun-loving African-American who's been in a few relationships and loves partying but right now, if you ran into her at a conference or something, you'd dismiss her instantly because she doesn't meet your silly criteria.
Also, don't be laser focused on marriage. If you go into all your relationships looking only for a wife, you're near certain to fail. Finding a wife (for me at least) is about getting to know someone first and deciding you want to spend your life with them second. It normally takes years for people to decide they're willing to make a commitment like marriage.
