I wish to remind you that complaining would depend on the country. In top countries, the tax is duly used that it makes sense to pay it as required. If you’re in a country where the tax isn’t used properly maybe due to bad politicians in power then I understand your why. I think the reason why tax isn’t asked from people with lower earning is because it’s not so much to get from them, and yet they’d keep struggling. As we can tell, wealthy people have more and the tax isn’t a lot for them to pay.
While taxing people could be quite annoying, but yes you are right, if they are the one who also benefit or majority will benefit out from those projects made through taxes, then I don’t think complaining will still be reasonable. After all, the tax they have to paid is just a small percentage out from their whole one month salary.
However, poor citizens are not required to pay tax simply because they also lack the means to pay for it. But if ever they also land stable jobs in the future, surely they won’t be exempted as well paying their taxes.
