Without taxes, society collapses due to the government not being able to do anything because they have no money. Companies abandon regulations and the rule of law in their quest to make as much profit as possible. Corners get cut to increase profits and avoidable disasters like the Grenfell Tower fire occur regularly.

Without government threats of violence to uphold the laws of society, what's to stop the wealthy from hiring mercs to murder your family and take their possessions? After all, don't they have a duty to shareholders to acquire as much profit as possible? What's to stop the masses of poor people from ganging together and cutting off the heads of the wealthy to take their possessions?

Taxes are absolutely essential for a functional society, therefore anybody who is completely and utterly against taxes (a.k.a deranged lunatics) is against a functional society. They want chaos so that they can exploit it for profit.

Rather than scrapping taxes completely, the tax system needs to be changed to stop taxing income and consumption which clearly hit the poorest in society the hardest. Wealth is generated from productivity, therefore productivity is what needs to be taxed, not income. Any tax on a worker's income is simply an indirect productivity tax on the employer which they pay through increased employee wages.

Most taxes individuals pay are actually indirect business taxes. If our tax systems weren't created by greedy, scumbags trying to funnel wealth to a tiny minority of people, those indirect business taxes would not exist and in their place would be a single tax on productivity from both humans and technology.

Essentially, productivity boils down to the amount of money that can be made from every $1 spent. The greater the productivity, the more money could be earned from spending $1. Given that the most productive companies make the most money from the least amount of work, people doing fuck up to earn shit loads of money would be taxed the most while those working the hardest and earning fuck all would be taxed fuck all too.

This is by far the fairest tax system I've seen so far.
