The govt has the power to tax people, not to make some feel better, but to promote the general welfare.
And how's that working out? Not just in the USA but all over the world? When the government takes to much in taxes they starve the people and distribute money, and rights, according to their own political whims. Government is necessary, but it must be controlled up close by the people.
The govt gets this power from the people, who have delegated this power to the govt. You can distort the justification of this power as being a feel-good policy, but that does not change the facts in any way.
Much of the government power has not been delegated by the people. It was just money, and then power, that the government assumed. They exercise their power and there is little, or nothing, the individual can do about it.
You will pay them what they want and if you don't you will go to one of their prisons, They have power over everything you own, with more control coming, and everything you earn. It is they who decide what you will keep for yourself, not you. And that power they have usurped from the people cannot be taken back without their final collapse.
And if the people support politicians who uses this power to gain re-election by doing what the people want, then that is a feature of democracy, not a bug.
If people want to give the government ever more power then the consequence will be like every government that has gained too much control in the past. The power will be gone from the people as the politicians try to meet the demands the people make of them. Then it inevitably all goes bad.
The interesting thing about this is that every people have believed themselves immune from this inevitability, that government can somehow meet all their needs and desires, that they can remove the fears that life brings and we can live without care under their benign and well intentioned guidance.
