Here's a solution ~ transfer 100% of FICA to employers on a graduated scale. Employers with less than 25 employees do not need to pay for those verified by E-verify to be here legally. Without e-verify, they have to pay it for all 25.
We ratchet that up on a logrithmic scale ~ so finally you get to UAW owned GM and they have to pay triple FICA for every employee provided they are verified by e-verify to be here lawfully. They have to pay 10 X FICA for illegals.
This taxes THE RICH and the POWERFUL CORPORATIONS.
Generally speaking, that’s not a bad idea.
