Considering you can go all the way through high school and take the same classes I did and apply for the same scholarships I did, regardless of living conditions when you turn 18, that's not really an excuse. Some people just don't put in the effort when they should, and then piss and moan later because it's not working out the way they wanted it to.
I can understand your argument if we're talking about someone who is in their 30's with kids already, but they obviously didn't make the right decisions when they needed to. Because I'm 30 and married with a kid already. And I still had all that shit figured out as a 15 year old. So most of the time, it is their fault for simply not caring or having enough initiative to take care of shit when they had the chance.
