Flat tax will kill any chance for low & mid-income earners for upward mobility....which means less dollars available for consumers.
Even with a flat tax, you will still need IRS to collect taxes and confiscate your bank account if you do not pay the flat tax due.
Only thing flat tax will do is push H&R Block and others out of business.
No you won’t need the IRS the money will be taken out of your check by your employer. Or the State or the Gov. !0% no deductions.. Period.. Businesses will pay no tax only the CEO’s Or Presidents of Companies!!
