If you are talking about the employer half of payroll taxes, we've included that in all our previous discussions-- employers match is 7.65% of labor. They do NOT match income taxes. We've agreed that business could save maybe 10% max, with corporate taxes included where they apply.
So, explain to me how a 10% savings for the employer is bad. Explain to me why the employer would need to cut my pay down to my post tax levels in order to save money. Explain how getting my full paycheck is a bad thing. I think we can debate the black market as a reasonable possibility. I'm just not real clear on your other points. Enlighten me please.
