I think it safe to say it will be a culmination of things.

A blockchain like Bitshares, which is designed basically as an alternative to the banking system could have a lot of impact directly on the banksters.

What Steem and Manna (and others do) is enable people to get out from under the slave system set up by the banksters where people are moderately compensated (at best) for the time the provide working. The fiat system is tightly controlled with most people participating in amassing debt as opposed to wealth.

Crypto changes all of this.
