A salary earner must think outside the boss to elevate himself to the next level in regards to wealth, though there are some people that earn higher salary but in all, your ability to think about a good investment that can help you grow your finances, money is not meant to be stagnant or kept in a place irrespective of the amount coming into ones pucket, it not necessary about owning a physical business but a salary earner must seek for a good investment thats capable of preparing him for the future uncertainty, a salary earner may be sacked or relieved of his position at anytime I think that's why they should be prepared to have alternative to fall back to in case of any ugly occurrence.
Buddy it is not compulsory for anyone to own a business but it is compulsory for people to have something doing or have a good investment in something that's futuristic.
Investment is literally the only way a salary earner could get rich. There is no way that salary earner could be rich with their salary, you end up putting some aside, and use that to invest and if your investment does well then you end up with a lot of money. However, most people who are salary earners, fail to put some aside, including me these days for example.
The amount of salary you earn of course matters, but none of us really make that much money to begin with, we end up losing most of our money back to debts and living anyways, so putting aside isn't that much for us, only for huge salary earners it could be possible but there aren't that many of them. This is why we need to be taking care of the fact that we are dealing with something nice here, if we can do that, then we will be fine.
