Lower middle class people, even though they have savings to open a business, they don't want to take big risks because buying a big bankrupt company certainly has to be considered, with the lower middle class, of course the amount of savings is minimal, maybe enough to buy it but not for the cost of operating it again so that it runs smoothly again, there is a possibility that if this happens, they will take out a large loan from the bank.
Starting a business is much more difficult for the poor because they have to consider and prioritize other needs in life. You can't start a business when you're struggling to put food on the table for your family every day, so there's nothing wrong with poor people prioritizing their daily needs.
Everyone has a dream of becoming rich but not everyone can easily realize their dream or have the courage to step out of their comfort zone for many reasons. Not all poor people are cowardly or lazy, and not all rich people are talented.
