It's easier to lower standards than to raise them.

There's always a race to the bottom. I don't think it's a big leap to suggest that what's considered the "minimum viable product" has decreased over the years. It's also no secret that software is getting worse.

As to salaries, I think you forgot how things worked before. The reason companies like Google introduced free food and all the incentives was because increasing salaries was not a better way to attract better talent, since salaries were already high. So either now something has changed where better talent cares more about money or we're attracting talent that cares more about money. As in either the same people changed or we're attracting a different type of person. Personally, regardless of age, regardless of field, I've seen a strong correlation with the best people not caring as much about money. Once the salary is good then they care more about how interesting the work is or how they can reduce stress in their life. Money matters, but it has decreasing utility as it grows.
