My wife and I come from poor families, and our parents didn't give us any advantages starting out. We paid for (borrowed) our own way through college, didn't get cars at 16 (or any age for that matter), didn't get any help after college, no house down payment, no cosigners, nothing. We paid for our own wedding ($10K, if you do it cheaply enough), and still rent an apartment at 30 years old.
My wife has a friend whose parents paid her way through college, gave her $5K to pay off credit card debt, paid for her wedding, gave her a huge down payment to pay towards her house, and her mom quit her job recently to move to Florida to take care of her baby full time. It's hard not to resent people like that who have it so easy in life because they had parents to help them out. My wife and I have advanced degrees, make decent money, but are behind because instead of saving for a down payment on a home, we're paying off $100K in combined student loans. So treasure the advantages your parents provide, and don't take it for granted.
