Can't believe this thread. Some people seem to lack heart and life experience. It's easy, when you are young, don't know much and haven't actually risked anything.
I know a thousand examples, and I share two with you.
1. Back in my small hometown there was this man, who came from a decent living working class family. He studied to be an engineer in late 70's and after working a while he started a small construction company in early 80's. By the end of the decade he was rich and successful, and a good employer who was dedicated to his workers - a quality which is rare especially these days.
So, because of his past success he felt confident in his business to take risks. He funded one tenement building with a bank loan even when he had sold only half of his last building and even when there were first rumors about deppression (a thing which people like GirlyGamerIC don't have an idea of).
Banks still used to give loans quite easily, a handshake and that was that.
Came deppression, the guy got his building ready but investors were alarmed and nobody was interested to buy flats anymore. Bank directors were sacked because granting loans too easily and unemployment percentage doubled in short time and suddenly whole country was filled with over-competent people. The guy lost his company, house, two cars, all of his money, wife etc. His parents had guaranteed his loan, so they also lost all. His father died soon after that. One of his workers, stressed about his loans and unemployment, committed suicide. The guy felt he was responsible of this all.
So, after accomplishing more in a decade than most of us can in our lifetime he became a houseless unemployed man without a future. Just because one of his twenty enterprises didn't pay off.
2. A girl I know was molested as a child by her father and uncle. She tries hard, but I guess every now and then memories get too difficult to handle, she starts to drink and usually looses everything she had accomplished in sober period before that. A vicious circle indeed.
