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.
Yes, it offers opportunities to everyone but not everyone can take advantage of it or not everyone who invests in it will improve their financial situation and become rich. In addition, bitcoin only helps us to fully control our assets but cannot help us have more jobs, increase stable income...
I wonder how bitcoin will help the poor and unemployed when what they need is jobs and can generate income. How will the poor own bitcoin when bitcoin is not free?...So it cannot be said that bitcoin is impacting the economy and helping people have better lives.
I agree with you, only we can save ourselves by taking advantage of everything we think can benefit us, don't expect or think that something will help us.
