CMV: There's nothing wrong with the 50s suburban "Nuclear Family"

Maybe this isn't as big as I think but I'm finding a lot of people my age and plenty of online personalities with left wing views are quite opposed to the so called "white picket fence" life. There's been a lot of pushes for urban density and denser housing. A lot of people are making suburbs out to be some kind of ultra isolated liminal spaces and I'm left wondering what the issue is.

Now, before we go further, I do understand and acknowledge the criticisms. It can make things very car dependent but a lot of suburban kids get sent to school on a schoolbus. To my mind, if you can get a schoolbus there, you can create a regular bus route. I also understand that it's almost impossible to live the same life on a single income these days but advocating for higher wages is not a bad thing. Also, with the advent of the internet, things are nowhere near as isolated.

So with that in mind. What's wrong with the suburbs. I would love a house on a hill with a yard, a couple cars, a trampoline for my kids and a bit of distance from the big city hustle and bustle. There's improvements that could easily be made.

EDIT: People are pointing out that I got a bit sidetracked and focused more on suburban life than the family aspect. That's actually very fair, I'll address that more focused here.

The "Nuclear Family" can be bound up in 50s imagery and that can have some negative connotations relating to race and gender equality issues. I'm absolutely not ignoring that but I also think we can have nuclear families without those issues these days. For example, two wives/husbands and their kids living together are also a "Nuclear Family", as far as I'm concerned. I consider a woman who works and a stay at home dad with their kids to also be a nuclear family. Also, I ABSOLUTELY do not consider it to only be white people.

I think if you want to be poly, or live with a huge family, ie: grandparents, aunt and uncle's, as is common in parts of Asia, that's fine. I also would much prefer not to do that.

I'd absolutely never allow my parents to hang out to dry in the cold but I don't want to live with adult sibling, their kids, grandparents etc, as a standard. It just doesn't appeal to me. I want to live with a spouse and my kids. I don't see what's wrong with that.

I know that those who want to "Go back to a better times" are often saying that they only want one type of lifestyle to be accepted and treated with respect. I'm absolutely not saying that, I want you to be respected for whatever home you choose to build for yourself. I'm also saying that I think "White Picket Fence" life, stripped of it's negative connotations is a perfectly positive and fulfilling choice to plenty of people and shouldn't be denigrated without nuance.
