I expect they probably have the same ideology I have, that this statement is very simple minded and throws very big well "you could just marry someone rich" vibes

Like yes the comment is genuine but it isn't reflecting on the fact that what the person is commenting on is the fact that societal expectations is that households required 2 income sources, which is polar opposite of what the society was built on where you used to be able to build a house and have a comfortable living with one income Source in the house, and now you can have two income sources in the house and still struggle to make ends meet. (hence the ideology of a minimum household wage instead of a min wage per individual)

Take my grandfather for example his house is currently equated at 300,000, he paid 14,000 when he bought it, this was with a stay-at-home wife and a household of four kids. My grandfather was a teacher, so on a teacher's salary he was able to afford that house and support his kids and his wife all with him being the only one who worked in the house. I believe that's the point that the commenter was trying to get at and it's likely why other people down voted that response. "Just get a roommate" doesn't address the actual issue at hand, it's a temporary solution to a hard set problem.

But that is just how I see it,
