Yeah.... along those lines.... government spends what it spends. It's going to raise the same amount of tax (actually more as years go by). Under the current tax system there are creative ways to avoid paying tax. In a consumption tax plan there is only way to avoid the tax. And that's to not buy new items.
Unless government is talking about cutting the budget, the average tax burden is going to remain the same. The highs and lows will just be shifted to different parts of the population based on spending habits.
WRT 23, based on what you wrote do you agree that a consuption tax does not provide a greater income and lower prices?
"Unless government is talking about cutting the budget, the average tax burden is going to remain the same."
That ignores the enormous savings in compliance costs and inefficiencies of the current system.
