You misunderstand. Your taxes are not for infrastructure. It's for a ships and planes, guns and ammo, and interest to pay our debt. It's to cripple our enemies and intimidate our allies. It's also to keep the masses of desperate people from starvation so they do not take to the streets, but you needn't worry about that soon.

You will sacrifice more for this system you see little benefit from. You may be called to fight for it, and you may even die for it, and the people who benefit the most from all of this killing and waste will eventually lose their hold on power due to the putrid state of the system itself.
