The key to success is luck
This is what I have learned over my 32 years on this planet. Everything comes down to luck. If you are rich - you were just lucky to land yourself into a good job and not have to suffer lay offs or unseen medical emergencies that prevent you from working. Or you were born into a very rich family and didn't even have to work. There is no other difference between the two classes of people: rich and poor, besides one group is more lucky than the other.
