Everyone is in charge of their own destiny. If you have worked hard but have nothing then;
You've spent more than you earned.
Simple as that.
YOU SPENT MORE THAN YOU EARNED.
If you didn't earn enough to sustain a certain lifestyle then in most cases that's your own fault. Everyone must make their own choices in life - be it what they buy, how much they pay for a house, how hard they study, how they apply themselves in their work etc etc etc.
It's all your own choices.
Don't get angry. Get motivated. Study. Change jobs. Take a few chances. Go without something. Try something really radical like saving a few dollars.
