Inheritance tax is just plain evil. Basically people in favor of this are advocating for the government to prey on the people who just lost somebody close to them (parents, grandparents etc.). Also the money, property, wealth a person gathered before death was taxed, bought and paid for. I know some people are jealous that someone else parents got their **** together and actually accomplished something to leave to their children, but we cannot create laws based in jealousy.
Well after you pass a certain threshold of income you naturally start to make some investments and diversify your income with it. So yeah virtually no one make the big bucks on wage alone, but people can be started on the path by the big paychecks.
