Not all people are skilled to have their own business and most people receive their knowledge to not build their own business but to work in a company that's why its hard to ask them to start their own business. Those people who work in the company are better to start saving their money on an asset like a house, gold, etc.
Everyone is born without skills and some people are born into business families. Can both of them be inherited or do you think they have the same genes as their parents?
I often see people who have no skills when building a business, but these people don't limit themselves to keep learning, so their skills and abilities can grow over time.
On the other hand, people who are born in business families, not even all of their children have the skills to build a business.
Everyone who dares to take responsibility for the business they are running will definitely get perfect results, otherwise people who don't want to try will continue to give reasons not to want to start.
Well, people have their own passion, we can't force them to have their own businesses and they have their own way to make a living. Also there won't be a businessman who has their own company if there's no worker who willing to work for him.
You are right in this, if everyone builds a business then no one wants to work as a subordinate in a certain company, we hear about this trait more often in areas that are lagging behind in terms of innovation. So it's easier to justify than trying to do something like building a small business to start with.
Finally, when this answer is given, people will be lazy to discuss how to develop a business and provide advice on the potential that this person has.
