This comment is spot on IMHO -- yes, of course it is possible. But it isnt desirable for many of us who went thru it.
I similarly grew up at the poverty line as my parents got crushed by double-digit inflation. Based on personal experience, I didnt want the same for my kids -- so we have 2 though we'd love to have 4.
This is the reason that we tell ourselves, but it isn't the reason why we stop having kids. If it were, the human race would have died out millenia ago.
Every single parent I'd wager that made those sacrifices and raised their family would tell you it was the best thing they ever did and that they'd do it again. If you've never been a parent you can't possibly understand it at all.
