I mean… you can choose to live in a less expensive area. Especially if one person is a software engineer where remote work is available. Will choosing to live in a different area mean you’ll go from making $500k TC to $150k or $100k? Perhaps .
We grew up in a duplex and my brother and I shared a bedroom for years because my parents wanted my mom to focus on taking care of us. I genuinely didn’t realize that our house was technically “worse” than my peers, until I was chatting to my dad about it last year and he mentioned the choice they made.
If you don’t want to make that choice, that’s OK too. I choose to listen to death metal music, I don’t expect others to make the sane choices as me. :)
