Example:
I have $100,000 to spend.
I can spend the $100k cash on a printer. Cool, I've got a fancy new printer. Nothing to run on it but hey whatever, I've got it and I don't owe anything on it.
Or I can pay someone else $15,000 (over 5 years) to spend THEIR $100k on that printer for me. Then I can invest that $100k of MINE into growing my business. If I play my cards right, I could turn that $100k into potentially $1,000,000 or more in new sales over the same time period.
One of those makes more sense than the other, to me anyway.
The stupid thing to do wold be to borrow someone else's money to buy equipment you have no need for, without investing in your company at the same time. I.E. living in a mobile home but driving a Ferrari because you could get approved for the loan.
