That is the thing! They make you to believe what they want you to believe and in the end you just realize that those who are suffering it the most are still the same set of masses believing and not liberating themselves in a way.
Paper is an inflating currency that the government keep printing just to cover up their asses, and with their bad economic policies, monopolies and a lot of shady things that keeps coming, you will just end up realizing at the end that, it just has been a scam all along and there is nothing good the fiat system on its own as well as paper currency has brought than negativity over the years.
