To answer the question, it’s simple. The US tax system is set up in large part as a scam on the American workers to transfer American wealth to the overlords who control the US government. It’s been that way since 1913.
No, to be fair, in 1913 only very high-income people were touched by the income tax. That’s how it was sold—a tax on the rich. It wasn’t until WWII that the average worker was touched by it. Then, there was no going back. I think it was during WWII that withholding was introduced as well.
The Tax System is just a complement to our Federal Reserve financial system - which really, truly does transfer wealth from the working class and savers, to government, its cronies and anyone who can access debt first.
