That's exactly how numbers work. Marginal increase of income from a single taxpayer is worthless to the government in isolation, and has zero impact for anyone. Hell, it's probably of strictly negative value if someone has to create a special account and procedures just for you.
Consider this as an illustrative example: if you were to suddenly start paying 2x the taxes you used to, literally nothing the government provides would change for you, or for anyone else for that matter. But if the entire country suddenly started paying 2x the taxes, you could expect much increased quantity and quality of public services.
Just like many private enterprises, government services too tend to have a lot of fixed costs, low marginal costs, and non-uniform access patterns.
If all people pay more taxes, a large majority of us will see a net benefit that outweighs our own cost.
I support raising taxes for everyone, including myself. This should not be a difficult concept to understand.
Are you suggesting that there's a magic threshold that needs to be crossed where individual contributions amount to more than the sum of their parts? If so, what is it, and why does it exist? And why does that threshold always seem to be conveniently too high for people who claim they want to contribute more?
Yes, of course having more money scales the ROI superlinearly. Lots of projects can't be done at all without a minimum investment. Others just have economies of scale (e.g. dilution of fixed overhead).
And considering that the government usually does stuff on very large scales, it's not strange that a single taxpayer's contribution is too small to be meaningful. Just creating a government program probably takes more than what I pay yearly.
No, I'd say they want millions of people to pay more taxes (including themselves) for everyone's benefit. The comparison is between an account that a few people can contribute to and not make a significant difference, vs everyone agreeing to raise tax rates and therefore have more common wealth.
Society benefits from taxes being spent on amenities, healthcare, education, police, when less taxes are spent everyone benefits less.
You don't want to pay more in taxes -- you don't believe it would make a difference, despite knowing how numbers work, and knowing that it literally would. I suspect you mean that the marginal difference for the government doesn't justify the loss for you.
That's fair, but it's exactly GP's point: you don't want to pay more taxes, because you don't care when there's no reward for you personally; instead, you want millions of people to pay more taxes for your benefit.
