Some would argue you're describing the status quo, which is crushing young people and the disadvantaged. How 'bout making capital gains equivalent to laboearned income?
That won't happen because capital gains and tax-free selling of real estate is the source of the power and inequality. Might as well demand reps sign their own economic death warrant or at least their own demotion to regular plebian socioeconomic class who needs to actually earn and be big boy taxed on their earnings to cover "their share" and attitudes towards how they are able and also required to spend their time
Except this tax everything scheme did not crush young people and the disadvantaged, at least not so much, in prior decades. The tax regime has changed, along with other parts of the economy. Maybe it's worth revisiting earlier years and analyzing all of their parameters to see what has changed.
