If you make more than your expenses, you are ok, no matter how much you make.
Uhhh . . . no. It depends how much more you make than your expenses, and what you do with the extra. Look at the budget most people have. What will they do if there’s a sudden emergency – car needs a major repair, the breadwinner loses his/her job, someone has a major medical issue? You need to have extra money stashed away somewhere in case it’s needed on an immediate basis. Many people don’t do this. The budget above does not provide for this.
