That's just how the nrst works.No it doesn't.There likeley won't be any "imbedded" income tax in GM's products this year. It replaces ALL (including GM's) income taxes in every dime spent.
They also have employer payroll taxes which are rolled into pricesWon't employee's get 100% of their wage?...How is that a savings?
There are two parts to the payroll taxes. The employer contribution and the employee contribution. But you knew that. You just chose to ignore it.
