I think, sometimes, you run into someone who is so strongly opinionated one way or another, that it's best that I just don't get involved. And somehow, I'm thinking this is one of those times.
Um, but I can't help but say this:
We have no choice over income tax, whereas we would have a choice in consumption tax.
That is, most of us have no choice but to work for a living. We have to, and that income WILL get taxed.
A consumption tax though? In the example of the yacht, you don't have to buy one. Or, you can and pay the taxes along with it. It's your choice, but at least you have a choice.
