This. The golden rule is to pay off your "Statement Balance" in full each month, thus accruing no interest month-to-month, but getting the added benefits of a credit card. When I was young I racked up credit card debt and it was an expensive lesson. Now I use credit cards for everything but never carry an interest-bearing balance. The upside: never at risk with disputes, additional insurance/warranty coverage, free flights/hotels/etc using points, and up to 30-day deferred payment on all purchases. Personally, I felt the article a bit silly. Especially when I reached the part quoting the PE-firm employee. I can't say that I know a single person who manages their money well that doesn't use credit cards. IMO, strong financial acumen equates to using any available tools to maximize your output and utility. As long as you spend within your means and do not accrue any interest, credit cards literally give you free [insert rewards program here] for doing what you're already doing day to day. That is the power & utility of a credit card.
