"What's this? The American working class is struggling because wages haven't kept pace with cost of living in 50 years? Surely suppressing wages even more will fix that!"
I'd argue the opposite. We print absolutely insane amounts of money, which is an indirect tax via inflation (and a regressive one at that, since the rich own more inflation-resistant asset classes than the poor, who don't really own any assets). Higher taxes and less money printing would make that hidden tax less hidden, which is good, but the core problem is spending/printing too much, not taxing insufficiently.
