You're ignoring my actual points to just restate your conclusion. Money you use to buy properties doesn't pay sales tax, money you use to pass on to your heirs doesn't pay sales tax, money you get to save because you have surplus only pays sales tax after you've gotten your initial capital out multiple times so the sales tax on the initial income is 0. But lets classify that investment gain as income as well and ignore that bit. Do you actually have any doubt that poor people spend a higher percentage of their yearly income on things where sales tax applies? That they buy less properties, invest less and then pass on less of a percentage of their lifetime earnings to their children?
