Google/Facebook employees: do something good for civilisation and quit your jobs. There are plenty of employers out there where you can create something real and positive.
This is not an argument or a talking point against immigration, or importing workforce, what I'm saying is that by doing this and (at least) not reforming companies(or better: shut them down), you effectively empower these corporations to be even less-principled and the pressure from employers becomes smaller.Now theoretically this can be curbed by the government, but there are a few problems here: you cannot do this and think you can remain competitive as a global power;such policies are very unpopular in US;FAANG companies can easily lobby and overthrown this(they already probably did and do this) policy;
So the solution imo has to be a bottom->up one: pressuring the company internally, though this rarely works in practice.Google has become more transparent (even if a facade) in the latest years towards the average user.But at the same time it has engaged in shady projects for the military that are very concerning,so who knows what's going on.
