The Panic of 2007 - from credit to debit cards

Here's another big financial transition that needs to take place. We switch from credit cards to debit cards.

The problem with credit cards. Do I really need to explain this?  Go online. Click, click, click. Buy, buy, buy. The seller in Singapore has no idea whether you can pay, your signature is worthless. 

With debit cards, the money gets transferred. There's real money there. 

Accumulating huge credit card debt just is too risky.  For buyer and seller. Individually, and collectively.
