military organisations don't have unlimited funding, they do however have the lion's share of the budget from taxation

without taxation, militaries cannot be expeditionary, aggressive forces

the original model for defense for the USA was militias, which were entirely self funded... soldiers were all like the same as a reserve force in that they did other work much of the time and maintained their training to stay effective

just keep in mind that prior to the Federal Reserve, the federal tax was like 2%, and the USA had no standing army before this, and if they needed money they basically would beg for it, mainly from the wealthy people whose products were needed and whose interests were in maintaining security

the modern social democratic state is an evil institution that grows like a cancer and consumes the wealth of the people, and gives nothing back, scaling government back to pre-20th century would be worthy of being called a golden age
