Given the existence of ticket resellers, I'd assume it's possible for a retailer to mark tickets as "approved for resale", although I'd expect the nuances vary by jurisdiction. Certainly, plenty of concerts charge sufficiently to exclude a large portion of people due to income, so the goals outlined above are moot for at least some concerts. Certainly, I'd support the ability of retailers to sell "scalping rights" or not at their own discretion.

I don't mean to be crass, but being able to afford more things is sort of the point of being rich.

I'm quite aware of the privileges of wealth. I'd assume the point of this sort of social policy is to offset exactly that...
