and rely on credit to run my business.
Credit is not a bad thing. For example, you own a bike store in Town A, which makes you $10,000 profit per year. You see that in Town B there is a big market for bikes, you coud make $20,000 with the same inventory, but in order to open a store, you need $100,000. You can either wait 10 years and save your profits to open a shop in Town B or take a loan which would cost you $10,000 per year. If you take the loan you will not only make and extra $10,000 per year, but you will create twice as many jobs in the process and double the size of your business.
If you don’t take the loan, you will not create the jobs, the bike company will not sell more bikes and you will not only miss on the oportunity to make extra $10,000, but you will also wipe out your profits for the next 10 years, since you will be saving this money to open the shop in Town B.
