Tia, I understand the motive but that's not how the consumer economy works, and not just in the US.
Of course, bad credit management can land you in hot water, but the proper use of credit is needed in order to get card or home loans. Saving for the entire amount (for a home) can take more than one's lifetime.
With the exception of home loans because it's next to impossible, like you said to get funds for a home without applying for a loan....
However....I highly encourage you to research the monetary system we currently use (United States - not familiar with other countries) because it isn't very old. And since we've been on the current monetary system, we've had several recessions because, as you stated, this country only survives when people go in debt. We're screwing ourselves with this, especially when people from both parties (borrowers and lenders) overextend themselves.
Our current monetary system is the sole reason we're in the mess and why we're going to have more recessions like this in the future. It isn't about credit but how money is backed up in value. A bank can lend on the same pile of money over and over and over and over, all lent out at the same time to lenders. When one domino falls, they all do. It's too unstable.
This isn't our only recession since the depression. We've had many smaller ones since then. I'm not an economist to give an opinion on what needs to be changed but something does. It is obviously not working. One little burp in the system and everything crumbles because everyone owes everybody else. That's not wise.
So no, I do not believe credit helps our economy. I believe it is an illusion backed by nothing that's as unstable as going to a federal prison, putting a pile of money in the middle of the floor and calling that a bank account.
What people don't realize is whenever you go to a bank to borrow money, the money isn't even there. The bank doesn't actually have the money
until you pay them back.
