i can't believe how many posters here defend this immoral nonsense taxing already taxed legally gained money

if the rich obtain the money legal way and taxed them why they should be punished for being more successful than others and responsibly leaving the money to children? basically what defendants of inheritance tax say you should not try to be successful because you will be punished by losers for it, it's income tax all over again (unless your country has flat rate for everyone)
