I read that article yesterday, but I just went back and read some of the comments.
It's a decent face-punch, IMO. It annoys me when people say the "deserve XYZ". I don't believe anyone truly deserves anything beyond food, shelter, safety, etc. None of us deserve anything, we just happened to land in a situation where we have a plethora of choices that most people on earth who work just as hard don't have.
If you replace vacation with brand new Lexus, there probably wouldn't be as much blowback. However, I think the author focused too much on just credit card debt - what about cumulative debt vs savings, interest rates, etc.? Way too simplistic. I have zero percent CC debt, but we also have paid off cars, hundreds of thousands in retirement accounts, etc., so that's a different balance sheet, and I don't consider myself a financial hot mess. I'm also only planning a short vacation by car this summer, where I'll stay with relatives most of the time, and I would never say I "deserve" it, only that I've earned the time off.
