Profit is not and shouldn't be the primary driver for whats useful economic activity. There is a lot of good work to be done that can't or won't be sustained by the market. Basic scientific research for example.
Who ends up paying for the decision to pay a meta engineer x, but the climate change engineer x/5?
It’s the engineer who picks the climate change job instead.
Essentially what you’re saying is that due to society not being willing to pay competitively, engineers should take the kick to the nuts and be paid peanuts to make up for societies bad decisions.
I mean sure you could argue that, as communists and others perhaps do, for instance, but we are chiefly talking about the US, where individual profit is decided, IMHO correctly, as the primary metric. Sure, you may want to choose to minimally do certain things for national security or other legitimate reasons as the people vote for (as I mentioned in three posts above), but that is supposed to be a deliberate choice of the people and their representatives, driven by their desires, not as an automatic subsidy to any pre-established business, in the form of lax immigration policy which can have second-order effects.
