This also has a disproportionate effect on the rest of the government, however. The wealthy clamor for tax cuts because they already pay more than everyone else (and as long as income disparity exists, this is going to be a fact, so it's not really much of an argument) which in turn means said tax cuts can break the bank so to speak. Which results in cuts to systems that the poor and less wealthy rely on to live, things such as basic schooling or financial aid.
In turn, that money that they do get tends to go towards things that entrench their power. Politicians, mainstream media, things such as that. I personally have not heard a strong argument for not taxing the wealthy and corporations more, because for all the tax cuts we've seen we're still in dire straits when it comes to dealing with poverty and healthcare. So clearly something isn't trickling down here.
Also maybe worth looking at how big of a tax break Amazon got for their R&D budget who only benefits... Amazon.
The thing that matters here is the rate, the tax rate and America has it wrong, I consume the same % as a wealthy person, my class collaborated way more (raw amount and rate) to the society than the wealthy.
Eg, To a pretty reasonable first approximation, all of Amazon's income is either going to be (1) distributed to shareholders and trigger income/capital gains tax or (2) invested in making goods cheaper for amazon's customers.
It isn't immediately obvious that it is a good idea to tax a system designed to get goods to people cheaply. The money Amazon reinvests in itself is in the short term all about making life better for its customers, not its owners. In the long term that reverses, but the reversal triggers additional tax events.
> It's ridiculous my tax rate is over 30% while wealthy people has it at 15%
The wealthy will be paying much more tax than you though. In raw amounts, the wealthy are doing much more to run the government financially than you are by orders of magnitude.
It isn't immediately laughable. A billionaire is making an absurd contribution vs. other taxpayers even at a 5%. And again, that part of their money isn't going towards themselves, it is difficult to consume that much in real resources in a year. It is likely going to investing in things that other people want.
There is no obviously-right or obviously-wrong with tax. Systems are complicated.
