Yes! a person or a corporation can have too much cash. A few even do.
Put that cash to work. Don't stuff it in a mattress, don't burn it. If you buy tools to practice your profession or art, that is an investment. If you start a company that employs people and produces a product or service that others are willing to pay for, and that covers your business expenses, that is an investment. If you buy stocks or bonds that enable others to expand or continue a business, that is an investment.
You may not have enough wealth, but you can have too much cash. Remember, cash, money that is, is only a way of counting stuff. Using it to increase the amount of stuff for everyone is the proper use of money. That . . .
