actually it is double dipping even.
One of the best luxury taxes is the VAT. You consume more, you pay more VAT. Sure not every rhich man consumes more, but overall they tend to.
And this can easily backfire on us other people. Why and how? (theoretical story follows)
Well there is this prick who happens to be CEO of my company, and hell he wants that sailing-yacht really bad.
We did a good job last year and the profit was fine, so after some number crunching he could buy his boat.
If he would have been charged more, we would have had to work harder in order to get this done.
Still very theoretical and simple but i guess you see where i am going.
most of the money the riches got, is earned by people like us. If we make them notice that it aint enough it is WE who got make up for the gap.
