I completely forgot about sales tax mostly because it isn't that high or notable imo, I always just see it as part of the purchase price which is my mistake for assuming that.It wasn't really a suggestion, it was applying the ethical principles put forward to a slightly comparable government enterprise. I don't think the sky would come crashing down, but I also don't think it's practical, considering there isn't a single nation that doesn't have them (as far as I know).
Also, apparently you don't have VAT / sales tax in the US? Jealous. Are countries without sales tax fucked? No. Was the US fucked when it had really low income tax? No.
I mean, that's all fine. These same arguments can be made in regards to mandatory military service, where that service is the price you pay to be protected in the country, just like professional military learns how to defend strategically.
Also I forgot how low your US taxes are. I gotta get outta here.
Sales taxes varies by state, but they aren't terribly high you maybe pay an extra 5-10 dollars on your groceries every 1-2 weeks depending on how much you buy or to look at it another way I pay maybe an extra 1 dollar or two when I eat fast food. It varies by state, so I usually don't think too hard about them as to me they're just kind of part of the purchase price. My apologies for possibly misleading you, though some states don't have sales tax and some don't have income tax at all (such as Montana), I'll use Florida as an example as I've lived there, Florida doesn't have state income tax but its sales tax rates varies between 6-8.5%.
Honestly taxes vary a lot by state so it is hard to explain what they are beyond US employment taxes which are pretty set in stone. I assume your country has paid healthcare if you pay so much in taxes, do note that healthcare in US is an issue in of itself so YMMV on how much that will benefit you vs the higher taxes.
I disagree that they're the same because the vast majority, unless they're mentally really fucked, can make income somehow. So anyone can pay the tax on that income, but not everyone is fit to join the army for many possible reasons physically or mentally. Little power level, but I have moderate scoliosis so my spine doesn't bend very well at all due to it being curved. I'm in some kind of back pain constantly regardless of what I do, and I'm a clutz that trips over themselves all the time because my body is not aligned properly. Not trying to fish for pity as I can still physically function fine overall, but I should not be anywhere near the battlefield as I am physically impaired to some degree from the get go which makes me something of a liability in actual fight and a waste to train for that reason.
Having a bunch of borderline useless soldiers still requires cost to board, train them, and equip them so you're basically just making a section of your army a very middling asset at best or a liability at worse while spending roughly the same costs as other more able soldiers. So why spend money on near useless assets, also if you force this much service how does it affect the actual compensation for loyal and generally more effective soldiers? Likely it'll go down to some degree unless you dramatically increase the miltiary budget. I guess you can make up meaningless jobs for crappy soldiers to do, but that sounds really inefficient. I know this isn't really an ethical argument, which is what you're trying to go for I believe, but to me the burden of the costs alone for miminal value is enough for me to say that forced service is a waste.
