I’m not getting you.
You can’t tax corporations - the customers pay the taxes, not the corp.
The “rich” pay the taxes to extent that top 1% pays like 20-30% of all income taxes.
So who are these “real” rich?
The people that have more than 90% of the accumulated wealth pay less than 1% on the passive earnings of that wealth. Their holdings are mostly untaxable under the laws of any nation, and they are able to keep it that way because they do have the power.
The result is that everyone else is taxed, and class envy is used to get the people to accept a tax structure that forever prevents them from accumulating any significant wealth, or benefitting from what little they can earn.
