We already know what the consequences will be and still don't do anything about money management, it's really stupid.
I agree with this since it is true that even though you are wealthy, there are still unexpected events that might happen. It is always important to be ready with those events by making sure that you have wide savings allocations. Emergency fund is one thing since it is really for emergency. Securing your financial status is an achievement and it would really help anyone regardless if you are starting to build your finances or even you are wealthy enough.
Most of those rich people are for sure already doing this because they are rich because they can manage their money well, so probably they already have emergency funds or funds in case they all went down. Though with us poor people, we have problems saving because it is not enough for us. That is why some of us prefer to spend it on food rather than save because our salaries are not enough. But even if I become wealthy, I will continue to save heavily for emergencies.
