The main culprits are our government's ability to print money, control interest rates, and disallow competing currencies. The videos do touch on these issues as well - they just don't feel like the main focus.
This is were you are wrong. Government has effectively one control of his money since JF Kennedy sign the executive order 11110 but was unfortunately never used... The FED is printing all the money and have all the real control over the economy.

I was using the FED & government interchangeably because both are required to accomplish the abilities I listed above. Without the government, the dollar would be worthless. We would have switched to a non-inflating currency a long time ago. The only reason bitcoin is succeeding is due to decentralization.
