Is the current economy/financial system good?

So i don't know much really about how does the economy/financial system work. From inflation to government regulations and everything… So the question is, is the financial system good? Or is it only good for those who can take advantage of the system.
Is there a better solution(Bitcoin, cryptocurrencies..)? Or is the curren say US financial system very good, inflation rate of around 2% is needed to drive the economy and so on?

Could anyone give a bit of insight about the topic?
