I think complaining will still work on some occasions but most of the time, not, it is because people always complain and instead of solving the issue, it only makes it worse. Preparation in life is possible but there is also scenarios that just can't be avoided, making us still experience a difficulty. Worse economic conditions are not new, especially to those who aged well already but there are just people who seem impossible to correct their attitudes. As you said, a decent living expense must be the standard or the minimum, so it must be okay to have one or two sources of income only but it's a different story anymore if we want to get rich.
Please complain and I don't think it will provide a conclusion to solving the problem in the current economic conditions and people will not really care about our plight because all they think about is how to enrich themselves. Although complaining is common because we have struggled and sometimes still fail, it will not help much. Every human being has a different story in terms of finances, but these different stories do not prevent us from trying to get out of economic difficulties.
A wise move is to try to work more precisely and collect money to start a business independently and after everything goes well then we can develop potential in investments such as bitcoin. If we are not the ones who start it, it is impossible for others to want to encourage us to achieve a better stage of financial freedom.
