Everyone gets to go to school for free, your taxes should be thought of as paying off your own education.
It seems silly to me that someone goes through public schools, then doesn't have kids and starts complaining that schools don't benefit them and they shouldn't have to pay.
What makes you think this is the correct perspective? Many Americans had parents who were educated abroad or not at all (if I'm paying for my education, what did my parents pay for?). Further, my education was less expensive than my education-focused-taxes are now - if I really were paying just for myself, shouldn't it be an inflation adjusted amount? Instead, I pay what it costs to educate a kid today.
We're not 100% keeping score here: some kids will die they day after they graduate high school, but on the whole people start lives as children, have a period of productivity and then are too old to really be productive.
I think it's not good to be bitter about supporting the young or old while you are working because you have been and will be (to some rough approximation) supported by the previous and the next generation.
Roughly 15 years of education roughly $5k annually at an interest rate roughly set at 15% interest (you have no credit history or school grades to showcase your credibility).
Roughly owing $150k at the end of high school, and building until you can pay it off.
Are you sure you want to make the argument that a public school education cost you many many times what a private school education would paid over a lifetime of taxes?
Of course not. There is nothing wrong with the argument you are paying for other people's kids. You are. It's a net good for society. I personal don't want roving gangs of uneducated youths who today are confined to schools all day, this is a big win for everyone. The day-prison system works well unless you're really interested in high quality education.
Deal with it, don't make weird excuses and pretend scenarios (like mine above).
I know that's how taxes work. The point is that there's no reason that should apply to purchasing internet.
Even if you think it should be government provided, that doesn't mean it needs to be funded in that way. Many government utilities are billed to the consumer based on usage. There's no real public good in forcing me to pay for other people's internet.
Something potentially offering a good to the public is not irrefutable argument that the government should do it.
