It
is possible to get through life debt free, but it can be very difficult depending on the situation.
Like my family- my parents work constantly with two jobs and have a busy life. My sister and I plan on going to decent colleges and get bachelor's degrees, etc. etc. But no matter how much we try, we can't just save money whenever we can and thus have enough money to get by without any debt. The thing is, we don't have any money to save in the first place. A large part of the country barely has enough money to put food on the table.
And my parents are well educated people, my mom is a High school teacher and my dad works at an amusement park and is a pastor. Yet we still had to go more than half of this year on food stamps. The only time of the year we ever really have any spending money is when we get our tax return, which is quickly used up on medical bills and expenses that we've waited on for far too long. If you've gotten by with no financial problems just by spending your money sparingly, you're probably a lot more well off than you realize.
