The sad fact of the matter is... math

A corporation might have 10 C-level guys dividing $50 million amongst themselves and 10.000 workers earning $70K, which costs about $100K due to overheads (health insurance, retirement, etc). Together, that's a billion, which is 20x more than the C level guys.

The C level guys aren't the big expense, not by a long shot.

Labour, government and shareholders divide most of the earnings amongst themselves.

For the record, I do think we need to tax the wealthy more and the workers less.
