The problem would be that total sales tax would be
around 25-30%. Even more incentive to avoid the
tax. People buying stuff off the back of a truck
would be the norm.

If you want to increase prosperity, just go back the
road you traveled to get here: reduce all taxes in
the order that they were increased.

Economic output will increase tremendously. Just
keep reducing taxes until the tax burden is about
8%. Right now it is about 60-80%.

Geez, people!

Let's just increase taxes every month by 5% What
is your tipping point? When 95% of what you make
goes to government?

If you were to receive a pay increase that doubles
what you are making, who would you want to decide
how to spend or invest the extra money, you or
someone else? You are the best person to decide
how to make yourself happy.

The average person pays over half of their
productive efforts to the government. Also, the
externalities of higher taxes creates more entropy
rather than synergy.

Instead of arguing about this particular tax, we
should be fighting for cutting taxes by 90%.

Or, we can just keep going in this same direction
