> The economy has grown substantially; corporate tax contributions, not so much.
Hey wait a second. Why should the PERCENT of corporate tax contributions increase as the economy grows? That doesn't make any sense. Corporate tax percent has been basically flat for 40 years.
The absolute value of corporate contribution has, of course, increase substantially alongside GDP. https://fred.stlouisfed.org/series/FCTAX
Personally I find the whole "tax the rich / tax the corpos" philosophy to be misguided. That's not how countries like Sweden and France pay for robust social services! They do so with extremely regressive taxes (20% or 25% VAT) and very high tax rates (40%+) at relatively low income rates (50k to 80k depending on country).
If we want to decrease inequality and increase social services then the average blue collar worker is going to have to pay for it. Taxing the rich is populism that cares more about being punitive than useful. But I digress.
