The burden on wealth producers is very low, one of the lowest points in the modern era.
You would expect in this era of hyper-rich and low-taxation that the wealth would be spreading around.
But it's not. Record profits for corporations (read: wealth producers) is turning into record stock highs, record numbers of billionaires and record lows for the middle class.
I refuse your argument because the world around me clearly shows that our "wealth producers" have figured out how to depress labor costs and increase investor returns. Great for them, but that concept is 100% contrary to your "wealth producers spread wealth".
No, wealth producers rightfully squeeze labor costs and rightfully return the biggest amount of money to themselves, their boards, and their investors. That's not spreading wealth downwards, it's spreading laterally only.
