1. It's pretty juvenile. I mean, do adults really need to be told that if they max out their credit cards, they make themselves poor credit risks and therefore lower their credit scores? Maybe the damage done by getting rid of their longest credit line is less mainstream knowledge, but come on.
2. While providing good (albeit very basic, No Duh) advice, it also feeds the audience a poisoned pill mixed in with the nutritious stuff- No, it is NOT a good idea to sign up for and use several credit cards instead of just one. That's actually really stupid, because it can lead to people masking their debt by spreading it over several different sources. It's also hypocritical, because this company- like every other credit-issuing company- will be quick to offer opportunities to consolidate debt into one card, as long as it's theirs.
3. In the end, there's only one reason to use credit cards beyond emergency situations, and that's to earn rewards points. I understand that rewards points are actually bad for people who don't hold credit cards because they raise prices for everyone while providing benefits for members only. I just don't care, because I'm a cardholder and especially because I'm a Boomer and everyone knows Boomers are all done caring about people who are not Them. Truth hurts.
