There are very few things that make people angrier than having to pay taxes. To some people this is an unfair thing to have to pay, but this is a requirement that the order created so that there would be proper financing for the entertainment that society requires in order to exist. The funny thing is that this means everything is an endless loop and humanity is not aware of the fact that they are working hard just to pay for their entertainment fix.
Paying taxes is a way to force humans to give back from what they earn, but indiscriminate taxing was something that humans started to use and this was not part of the original plan that the order had. The only problem with taxing people with low incomes is that they get very frustrated when that are unable to keep enough of their money.
