for those kind of people pursuing career by working 9-5 is nothing wrong, they enjoy it too, after all entrepreneurship or even investment is more difficult than what it seems.
I've seen plenty of people that enjoy working 9-5 because they just love the job themselves and willing to go work overtime and be fine with it even without increase in salary over the course of the year committing to the company they worked in and be fine with it, sometime life is not all about salary and I do agree, do whatever we find pleasing.
also, this rat race thing is just not really a thing, some people that thinks they are in a rat race working 9-5 simply put just don't enjoy their lives, they are too fixated in earning money that they forgot that there are something more than earning money, of course i could be wrong in this regard but at least thats what I viewed so far.
There are positive and negative sides to every business, some people like to be an entrepreneur, others find it easier to go to work and get paid, but I first mentioned that it matters where you work, because in one country the salary can be 500 dollars, and in another 5,000 dollars, that’s the whole difference, but the country’s standard of living will most likely allow you to live with an average salary, and the person will decide for himself whether this is enough for him, or whether he wants more.
