It's amazing the power they have to make up new "rules" this broad without a vote by elected officials.
In the US we need to abolish the income tax, corporate tax, and all of the other federal taxes, and add a VAT that scales higher for luxury items like houses over certain values and luxury items.
This would end up being far more progressive that the shit show we have today with the tax code. It would also lower stress levels 10x.
We also need to revoke the bank secrecy act and patriot acts. We can put in a streamlined subpoena process if law enforcement needs access to financial records for a legitimate investigation. We're not living in the 1970's anymore. The rules are archaic and overreaching and allow for total financial surveillance without a warrant. That's just too easy to abuse if you have access to these systems.
The first thing I would do if I was an evil person is put plants in government who have access these systems. The power they wield is enormous.
