The Rich set up politicians to maintain and expand PrivatizedGovernmentPrograms. PrivatizedGovernmentPrograms cost too much to pay with cash on hand, so the US Treasury has to offer securities in order to get enough Federal Reserve Notes. The Rich buy the securities and the Treasury deposits the FRNs into the Federal Reserve Bank so that the government can start writing checks to the rich who run PrivatizedGovernmentPrograms.
Then, the rich-owned politicians give the rich a tax break.

The PrivatizedGovernmentPrograms keep demand for food (by EBT), real estate (by Section 8 housing), medical goods and services (by Medicaid), and college education (by scholarships and loans) high. Higher demand means higher prices.

Government spending drives inflation. Government borrowing drives up interest on loans.

Simple words. Simple facts.
