Also, "half" doesn't matter and I shouldn't have mentioned it. What matters is OP made a serious statement and then the comment I replied to dismissed it out of hand. Regardless of total percent, its a view which you will encounter at a level high enough that this sort of dismissal has effectively shut you off to a very large group of people.
What are the principled differences between income vs other (sales, property, inheritance) taxes? And why does it matter whether it is at a federal level? We still need services at federal level, eg. to run our armies who are essential to deter potential invaders.
So what? They followed a due process of getting the amendment ratified, which means there was overwhelming support for it. Seems pretty legit to me. If you don't like it, pass another amendment repealing it. If it is truly bad and people hate it, they will repeal it just like what they did to prohibition.
> an income tax brings a double tax.
And so? Ultimately, we the people want stuff (medicare, social security, defense, national parks...) so we gotta pay for it. If you think you have a better alternative, propose it. If you think the stuff people want is frivolous, propose repealing all that spending and see if people buy into your vision.
First, I don't think half the US population seriously thinks taxation is theft. Mainly because a vast majority of us support medicare and defense spending, which are funded out of tax.
But this is where you get into "unserious" territory. Let's say everyone agrees to abolish taxation. That means no government, which means no government services, which leads to a lack of policing. In that world, who is going to enforce your property rights? Only thing ensuring things you consider yours stay yours is if you are stronger than everyone else.
Are you saying that half the US population really want to go back to eras when you only trusted your own tribe, wars and pillaging were rampant and only the might was right? If you don't intend to say that, then please explain who will enforce property rights in a nation of 330M people without any services funded by taxes.
