I strongly disagree with most other liberals on the inheritance tax, or on the notion that accumulated family wealth is a bad thing.
I personally live a lifestyle incompatible with my own ability to generate wealth,
so the ability to do so is what makes life worth living to me.
My fellow liberals go completely off the track when they think in terms of unnecessary economic ceilings rather than necessary economic floors.
Further, it's quite clear that wealth can be and is generated from scratch as technology evolves,
and that acquired generational wealth also dissipates with time.
One other thing. If some measure of inheritance tax needs to be applied, it should only kick in when assets are liquidated to cash.
If inheritors want to keep things like businesses or mansions, or art collections or whatnot intact, they should be able to do so.
If they want to liquidate them for cash, then some reasonable tax might be applied.
