The Nazis never sought to "enslave all", they had figured it that 10% of the population were to be exterminated, and only about another 10% to 15% enslaved by the state, and then their labor contracted to corporations which in turn, paid the state for their labor. It was in part based on a government system that would be supported by slavery, but the non-government portion of the population would be fairly "normal" by most standards. As a matter of fact, the Nazis were shooting for a lower peacetime incarceration rate than the US. Eugenics, the concentration camp system, and a lot of other theories were learned and exchanged between US criminal justice authorities and Herman Goring in the early 1930s. In fact, the Nazis in general had a distaste for using prisoners for fatal medical experiments like what was being done to black prisoners at the time, and infamously by the Japanese. Mengele was more of a sick puppy than an exception to the rule, but fatal wartime experiments were done on a limited basis by the Nazis after everyone but the Japanese had dropped the idea. In fact, technologically, the Germans were at the back of the pack when it came to Germ warfare and it was the threat of anthrax and Germ warfare that really got them to back off from finishing off Great Britain.

A majority, even under Nazi rule, would benefit from it. Once productivity and public need reached a certain equilibrium, both the military and slave worker populations would be reduced. Slave worker attrition would be faster than their birth rates while military numbers would be reduced and former military personnel divided between the labor force, and administering conquered territory.

Much of the Holocaust had as much to do with screwball Nazi occult beliefs as everything else, but the idea of "ethnic hygiene" predated the Nazis. In fact, it was more openly done in the US in the early 1900s.

The question is when that rule is maintained and expanded through aggressive war and terror.

I just would not have a problem paying taxes as long as the people collecting the paychecks from it were not focusing so much effort on taking away our freedoms.

Why the hell can't they do something smart with the money that people can visibly see and use, like roads and bridges? Heck for that matter even public housing, but straight infrastructure, that is a good legacy and shows that any administration that was into building actual concrete infrastructure had the public good at heart.

Notice how few people were bitching about paying taxes during the Eisenhower era when so much stuff, including the interstate highway system, was getting built.
