There have been studies of poor people who win multi-million dollar lotteries. They are generally poor again in 1 to 2 years. It is amazing how they manage to burn through so much money.
The difference between rich and poor has been proven to be in the spending and saving habits. If a poor person has extra money, they immediately spend it. They also don’t want to cut back. The prefer to try to spend like they are rich.
People who became wealthy (as opposed to inherited weath) try to find ways to make that extra money work for them.
Banks make money without the ‘vulnerable’. You are forgetting construction and business loans for large companies. It would be interesting to find out just who this
‘banking industry chief’ is.
