Don’t have a bunch of kids and a wife if you cannot afford them.
And when most families run up against that, then our country has a demographic disaster or an immigration / cultural disaster.
(In my case, wifey and I planned to have 2 kids and adopt 1, choosing adoption for the “1” mainly to not be a hypocrite to our pro-life views. We ended up only being able to have one - she’s our own blood.)
