Hang on middle class.... he is talking about taxing your income. But he dosen't want you to know about it, so he won't try to raise your tax rates and have that reflected in your pay check.
No, he wants to eliminate tax loop holes (credits and deductions)... you won't see this reflected in your pay checks, it will be hidden in the complicated tax filing forms. So you won't miss it on a weekly basis. It will be taken from you by either you owing something more on April 15th or any refund you get being smaller (which really is the government giving back the extra money it took from you...)
So hold on... the real income is in the middle class. As the rich have wealth, not income... so this won't hit them. YOU are the TARGET this time!
