> i don't agree that debt is the problem

Totally fair, by no means is that a settled issue. Debt is just my opinion of a likely root cause.

> there are lots of redistributions that are net beneficial even when you account for the incentive hit. marginal increases in the estate tax, for instance, almost certainly fall under this umbrella

That requires a lot more context to answer. The costs and benefits considered are important to lay out. Without that context I really can't say if it's a net benefit or not, I would assume that two average people would have a different list of factors they'd consider when saying whether its a net benefit or not.

Personally I don't see estate taxes as net beneficial. I don't agree with the principle that death is a taxable event, and I don't prefer the government to have in incentives to see people die (i.e. when someone with an estate dies the government makes money). Financially, to stick with just the numbers, I don't consider $66B in annual revenue worth the bureaucracy or legal complexity required to manage the estate tax program.
