Well technically cash is only worth what the government says it's worth. It's just a bit of paper saying "I'm worth xx".

I use a debit card, have no credit cards, and thus no credit card debt. I don't feel all that sorry for folks who complain about their own credit card debt. They are adults who choose to spend money they don't have, and then they owe the money back with interest. It's just a loan that you get from the credit card company, lots of small loans, all of which accrue interest.

People lived before without credit cards, and there's a percentage of us that still live without credit cards.

I'm not all that worried about big brother cameras. I think most people worry overmuch, because really.. who in the government is really concerned that YOU are going into wallyworld to buy some popcorn and toilet paper?
