Wages are not proportional to skills or output. Wages are only proportional to power.
So a low agency explanation is that supply exceeds demand and companies are either tacitly colluding (by flooding the workforce with layoffs to increase negotiating position) or actively colluding (like google and apple did).
A high agency explanation is that collective bargaining via unionization is in decline and people either need to unionize or guild to improve their power, but aren't because that involves putting oneself at risk for the benefit of others.
Also, the public markets have gotten wise to VCs Ponzi scheme of capturing all of the value of a company before it goes public, the company still not being profitable when it IPOs and then the public seeing the value of its investments stagnate or decline.
Without a viable exit strategy, investors are a lot more skittish about throwing money at startups.
Yes, I know most exits are via acquisitions. But in the current regulatory environment globally, major acquisitions are also being blocked.
Salaries haven't gone up much or down from the last eight years in big tech, it's stock comp that has gone through the roof, and that is an artifact of companies having to entice employees to leave their appreciated, unvested shares.
In addition, huge scaled up deca-corns were offering huge comp packages (higher than FAANG) to make up for their loss of liquidity, so the profitable big tech companies had to pay up to at least retain some of their employees.
There are a lot less giant scale ups these days, so you're seeing less focus on retention packages.
That being said, the right candidates can still go get ~$350k from Amazon and more from other FAANGs, etc.
1. Significant decrease of funding available for speculative projects due to end of ZIRP in 2022.
2. Oversupply of people who want to work in tech due to overhyping and perception of that being easy kind of money until the crash happened. #learntocode, they were saying.
Also cost savings and efficiencies are in play and so salaries may be influenced
