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.
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.
It's because there are only two types of people in this world:
1. People who takes advantage
2. People who likes to be taken advantage
So, of course, we cannot really force them if they only wanted to work because their mind isn't programmed to be unique and only follows where there's huge crowd. Besides, there's a reason why we're here in this forum learning and discussing some things while are busy following their boss because they are not the ones who are in total control.
And I agree that not all people are skilled to have their own business, but that doesn't also mean that they aren't skilled to have their own investment.
Good argument, even they don't own a business but the chance to have investment is possible, like what you said, there are situation where people tend to stay with day jobs and follow the flow on how their bosses wanted them to go, which very common once you are dealing in surviving life.
But, it's doesn't mean that you are limited, we do have equal opportunities, some might be luckier as they find an investment that can bring them to good financial freedom while some are trying hard to learn additional skills to find their spot in whatever investment or whatever other income source that they can generate.
