SWEs have more bargaining power than ever right now (at least in the US, which is the market I'm most familiar with) .

The only big change in employment in the last 15 years happened outside of software development: the gig/sharing economy.

1) Plenty of people in finance, lawyers, and so on have high salary and excellent conditions. Many had highly paid jobs in the same fields 50 years ago. This is nothing close with "disrupting the traditional employer<->employee power dynamic".
2) An this point it's really difficult to assume that you are arguing in good faith.
It's nice to have your role in high demand, but all good things must come to an end.
Perhaps this isn't the union that will do it, but surely the tech industry can find a way to innovate on unions and labor power. Why everything else and not that?
