I agree with you, but my hypothesis is straightforward -- it's the money. The internet in particular, but tech more broadly, is now a mainstream industry, generating and attracting a lot of money. In the US, even a poorly paid SWE, for instance, is almost certainly making well above the median income. Decently paid SWEs make a lot more, and well paid SWES... And of course those who actually employ well paid SWEs and are only paying their developers the least they can get away with, while still paying them a lot, are obviously raking it in.
There's good and bad in this, but it does clearly change things. When there's that much money on the line, ironically the stakes become higher and there's less genuine creativity and risk taking. The flip side is of course true -- too little money is a problem (I mean, I'm not about to trade my SWE gig for working in an Amazon warehouse as a means of spurring personal creativity), but given enough money past a certain baseline, things do change. There's a sweet spot at "enough money that people can feel free to be creative and take risks" and "so much money people are scared to take too many risks".
