The comic works because buying a house is harder than in the past and trying to convince some people of that is often impossible.
I never argued it’s as easy as it used to be. I mean, I didn’t buy a house when I was a baby, but my parents did (when I was a baby, not them) and they didn’t have any issues afaik. I surely had to work way harder than they ever did for a home that was arguably worse in quality and I never said otherwise.
The comic to me seems to imply the idea that to buy a home you’d have to do something ridiculous and unreasonable (such as letting your dad die earlier), which isn’t the case. It is more ridiculous and less reasonable than it used to be, I’m not arguing that at all.
