Pushing salary lowers help the society at large, or at least that’s the thesis of OP. While it sucks for SWE, I actually kind of agree. The skyrocketing of SWE salary in the US, and the slow progress US is making towards normalizing/reducing it does not help US competitiveness. I would not fault Meta for this though, as much as US society at large.
SWE should enjoy it while they can before salary becomes similar to other engineering trades.
It's great to enjoy programming, and to enjoy your job. But we live under capitalism. We can't fault people for just working a job.
Pushing for lower salaries won't help anybody.
