In the US, not having a credit card is horrible financial advice.

You're paying an additional 3% on all transactions, as that's the standard credit card processing fee.

You're also failing to build up your credit score, which is pretty important if you're ever looking to rent or buy a home.

tradeoff is harder access to liquidity -- would banks be willing to give as much credit without credibility?
