Well, that's a very glass-half-empty way of looking at it. I'm saying that high earners have to help subsidize lower earners the more luxuries they accrue in their life. It's not the earning after all that makes the difference between rich and poor; that's why the wealthiest people in America pay no income tax. They're not earning anything, officially. But boy do they spend.
So maybe, I don't know, if you're really concerned about people getting that one luxury in life then there could be an exemption, like if you make under $50k a year you get refunded the VAT on $2k of luxury purchases. Ok? But it has to be small enough to prevent the ultra-wealthy from using it as a loophole.
