I agree with the description, but am not sure if estate taxes solve the problem. To whatever degree we tax estates, corporations also have to be taxed. Removing money from the ownership of individuals would give corporations tremendous power advantages they don't currently have. People tend to like the idea of taxing corporations anyways, but that's probably worse than taxing individuals based on investment reduction rates

I tend to consider distaste for the silver spoon a red herring that doesn't solve any problems. The wealthy usually become the most educated and most productive, largely because they have to in order to not go broke. There's a whole lot of flux in whose wealthy and whose not, and I don't see that many examples of de facto dynasties through estates (none, actually).

Overall, I guess I just don't support taxing businesses or individuals. Tax sales. It's the easiest thing to meaningfully quantify, and the encouragement of savings would overall make the economy far stronger and wealthier.

Also, I'm pretty sure Paypal, Tesla, SpaceX, and Solar City wouldn't exist if it wasn't for one dude having incredibly rich parents
