Earlier quoted context omitted.
I think in general luxury goods taxes are underexploited. People normally want to buy expensive things so they can show off how much money they have. May as well make them more expensive, and divert some of that cash to useful purposes.
Maybe... My point was that often these taxes are actually targeting imports, and not necessarily "luxuries". Well, that also depends on how you define luxuries :) I personally don't mind taxes, but consumption taxes, even on "luxury items" are generally likely to be regressive in nature. So maybe don't use them...
I'm not sure. I was just looking for some points of comparison, and as far as I can gather, tampon tax (the standout example for regressive luxury taxation) wasn't actually a luxury tax, but rather a tax on 'unnecessary' items. Which is - ech - but, you know, it's not an extra tax.
I think explicit taxes on higher-price items within categories (so like, expensive cars) would be kinda nice, because it avoids all of the fiddly questions over what is and isn't an luxury item.
