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.
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.
