When the cost of the income tax is removed, prices will fall, THEN you add the national retail sales tax and prices come right back to where they were.
Slow down and read more carefully - it is not double minded ar all. One thing happens, then the other. The end result is that prices remain stable.
Did you really think someone be so stupid as to say two different things?
How about that! Two trillion dollars just appear out of thin air! I am impressed, usually it takes Congress and Liberals to come up with magic acts like that. Where they say that a product whose net cost was 'X' yesterday will be 'X' tomorrow and no one will ever pay an income tax again. Plus the majority of people will receive a check from the government at the end of the year. I call BS, the numbers are bogus.
But to deal more directly with your statement that products will be cheaper by 20% (and those numbers are massively inflated), lets go back to the story of two homes. Now you say that the olderhome will not be taxed when sold. Given my scenario where a person contracts for a new home to be built during this amazing 20% savings universe, it still makes the new house cheaper by 20% which exceeds what most people have in equity in their homes.
I really like the tax'd only once to the original owner. I am going to pull a Donald Trump and leverage myself into contracting to build billions of dollars worth of housing before the sales tax, and then sell the houses as "used" in the new economy. Dittos with fleets of cars, trucks, furniture, boats, aircraft, whatever.
I am all for this now. With massive quantities of debt I will be able to retire a trillionaire.
