As a 23-year-old, I don't know a single person who has gotten kicked out at 16 or even 18 and had to make it on their own. I know a couple who have had to make it on their own (including myself, since 20) but we weren't "kicked out," we still had people to rely on in an emergency or for a short-term loan (eg, I borrowed a few grand to buy a car, paid it back in a few months with interest, much easier than trying to get a bank loan for an old car...).
