There is a two-step process here for your builders, gardeners, nannys, security guards, etc. First the things they want must be produced, then they have to secure access to those things.

There is no question that tax-and-redistribute can make step 2 happen. However, the problem is that the plan for step 1 is usually some variant of 'Massive taxes aren't going to change what gets produced. What's gonna happen, people gonna stop working on important things?'. That plan often doesn't work because it turns out massive taxes change what gets produced, often much for the worse.

You can get morally outraged if it makes you feel better, but your comment inspires no hope in me that you've thought your solution through. There is substantial evidence that, economically speaking, going for a big pie unevenly shared is a much better solution than going for a small but evenly sliced pie.

Who am I protecting from taxes again?
