I read that 60% of wealth in the US today comes from inheritance. That's aristocracy.
Is there something wrong with earning wealth and then passing it to your children? Why are strangers or government more deserving of it? It's your money, you earned it, you should be able to give it to whomever you want.
As far as I know, at least in Canada if you inherit money it's counted as income, so its taxed there anyways. I get the argument about super wealth concentrations, so go tax wealthy incomes above whatever ridiculous amounts.
Everyone should be able to have their basic needs met: a roof, healthy food, high school education, necessary healthcare, basic physical safety & security. The US doesn't even have that yet for everyone. But after that, it should be fair game and nobody deserves anything from anyone else.
