The second reason why you can never become rich is not knowing how to use money. There are several ways money can be use : spending, savings, and investing. Many of us already know about spending and even when we spend we spend on things that are not really needed but just to impress people who don't care about you.
The different language placement of the two examples we are trying to discuss can prevent someone from getting richer. So what if people don't have money to allocate to savings, investments or running a business? These are two different and very foolish examples when people with more financial means are unable to allocate their money towards investments, savings or business.
Buying liabilities, things that doesn't have value five years from now. Many save but even when money is saved, it is done to spend and not to invest and the only way to become rich is to invest and not by savings. So , invest in assets and not liabilities.
I agree with the point of the value of money that we have in five years, when the money is saved and even though it is not used it is also unproductive because its value does not change or it may decrease. It's different when the money is used for investments that can maintain the value of the currency or try to develop a business that can be developed, this is where the ability to recognize a good investment or make a review of the business you want to run.
