True that, but don't you think it is the people who invested in Bitcoin to integrate into different applications are the ones giving or providing employment? Bitcoin is just a tool but companies and people are the one giving opportunity for a job.
Bitcoin was created first by Satoshi Nakamoto, not for fun, but its utility and use cases didn't appear immediately and its utility and use cases were not accepted shortly after its launch.
With time, more developments done, more educational and marketing efforts from developers and community done, hence Bitcoin has increasing and better adoption. When adoption was big enough, people started to build up an ecosystem around Bitcoin, with companies, products and available jobs.
No... I think it is the people themselves that rescue themselves by taking advantage of Bitcoin volatility and growth. Bitcoin won't be able to rescue anyone unless these people invest their time and money in improving their financial status.
It gives everyone great opportunity to improve their finance by investment into Bitcoin and have better control of their funds rather than dependence on banks.
With Bitcoin, if people can have their Bitcoin private keys/ mnemonic seeds, they have their bitcoins - it means they have full control of their bitcoins, not like money stored in banks.
