Simple hypothetical, no condescension intended, but when do parents, in a standard household with means, stop feeding their children? When do they stop paying for their car insurance? When do they stop providing basic necessities? We have the outliers that never leave the home, but the vast majority of kids find themselves on their own in college or when they leave the home. For example, I was on my own dime for most things from the age of 19. I grew up knowing, because it was taught to me, that eventually I will be an adult and that my life will be on my own dime. My dad paid for my cell phone when I was in college, but it was commonly understood that when college is done, I'm paying for my own phone.
There is this fear that "once you start feeding them, then you'll never stop." Our own personal experiences with our own families tell us that isn't true. If children who are in need are educated and prepped for life as an adult, they will know, just as you and I did, that when we venture out on our own it is with the expectation that we learned to take care of ourselves. The old adage "give a man a fish... teach a man to fish" leaves out the part that you didn't let the man starve while you were teaching him.
