The question begs, is there a way to get rich even if your expenses are higher than what you are earning?
Under this circumstance, you're just going to keep working your ass off and keep borrowing and borrowing with nothing to show for it. The only way you can get rich is if you win a lottery or something.
Some people might use credit cards or loans but it is just a cycle of taking a loan then paying it and you are not really moving forward are you? Saving also does nothing much but it can be a good start. You start saving money and at some point when the money is big enough you can start investing.
You are right. Except you inherited wealth from somewhere, but if you need to start from nothing and walk your way to riches, you've to save up and invest, there's no two ways about it. Invest the money as it comes in a business, and little by little and you can turn a small business into an empire.
