Yes, he is. Now, the preponderance of replies from FReepers about using a credit card (on a Dave Ramsey thread) will be from posters saying they pay off the balances every month. The posters mired in revolving credit don't really post that they're happy with 5-digit unsecured debt.
Dave helps (ok, advises) people break their dependancy on credit with the only exception being mortgage balances. If everyone took Dave's advice, our economy would look vastly different (for the better0. Of course, that's just my opinion.
If correctly used - and that would involve paying it off monthly (or having a plan to pay it off) - I don't see the problem. BUT, I can see how less responsible people could quickly get into trouble.
They've tighted limits a lot. I recently picked up a new gas CC - the program got cancelled on my old one, so they cancelled the card as well...I could 're-apply for a new card at the low, low yearly fee of...'....forget it.
Anyhoo, all of my CC's I've had for years and years. Their limits that run from 'high' to 'foolish'. This new gas card has a limit high enough for me to buy a month's gas on, and not a whole lot else. Which is fine, because that's what I wanted. But I still thought that it was interesting - and likely a good thing - that banks had tightened up.
