Fair point. Most people don't know or care how the economy works, left or right. My main point was: it's to your advantage to know how the system works, and it's maybe even more important to understand how it works if you hope to change it.
If you don't understand what is inflation and its impact, or basic economics, then politicians can take advantage of your lack of knowledge, in the same way a shady car mechanic can take advantage of uninformed customers. They might pretend that certain policies will help lower-income people when what they are doing is most beneficial to the ultra-rich.
