I can see this from both sides.
My husband and I started life on a bottom rung. He was raised by a single father (from the age of 2) without much money. He suffered horrific abuse by a babysitter, ended up in a group home, then foster care, before returning to live with his father (who is a lovely man, just to be clear). He left home at 18, with no money, and no prospects.
I was raised by a mentally ill mother, and an abusive (in all ways) father. I was put into care 9 times before I left home at 15, with 30$ to my name.
Statistically, not great odds of success.
We had a child at 19, married at 20, and had another at 21.
We worked shit jobs, often for 12 or 13 hours a day, to make ends meet. We live in a city with less than 0.5% rental market. That means it is a major struggle to find housing that is affordable, and safe.
We put ourselves through university through loans, no help from any family. We were able to make ends meet, but just barely. Eventually, we managed to get into subsidized housing. That was good luck, as the wait list is around 2 years.
We looked around, and realized that our lot was never going to improve if we didn't make some major changes.
DH signed up with the Canadian Forces. He was willing to work damn hard, leave his family for over a year, to be able to get ahead. It was hard work that got him through, not luck. He is now in a position earning 25% more than he did a year ago. He has job security, an oppertunity to have health insurance and dental care for the family, oppertunities to progress up the career ladder, and a pension to boot.
It means we will have to move thousands of miles away from our family and friends. This is going to be hard starting over, with a teenaged daughter, a son with AS, me with depression, and knowing no one. It will be worth the sacrifice to have a better life.
We didn't start out with oppertunities, but we are wiling to work hard to get them. Having a better life now will not negate the hard work, stressful jobs, and rough times we have come through. At the same time, I know that life can turn on a dime, and someday we might find ourselves having to start all over again.
Phew, that was an essay! Sorry so long!
