I'm a nepo buyer ✋
My American Boomer parents view helping my sister and I out with things like this as a legal early inheritance transfer to make up for how long we expect their lives to go on. In that way, this isn't really different from being able to buy things because you received an actual inheritance after your parents died.
The problem isn't the people who are able to do this. The problem is that other people for generations have been systematically robbed from also being able to do this. We should have government programs to provide this service for those people to make up for that generational theft.
Also: Jesus, Canada, build some fucking housing what the fuck. I knew it was bad, but I assumed it was on par with the US.
