Inherited wealth is typically earned from unfair business practices, in America the most glaring one is slavery.
When you inherit wealth in an estate that's income, so it should be taxed. You are not taxing the person who died, you are taxing the person GETTING the money, because it is income. Why would this income be any different then if your parent just gave you money? If my father gave me a 100k right now it would be taxed so why wouldn't it if he passed and I inherited. Inherited tax is not "what is wrong with the world". Try not to be so fragile lol
