Let's assume that you have group A, in a position of power, wealth, education, connections, etc.
There is also group B, which has none of that.
Let's assume that naturally group A doesn't want to give that up. If you don't agree, you don't know enough about human nature and I'd really like to see studies that back up your opinion.
Let's assume that most people are ordinary and statistically most people don't break through to a higher position.
How do you equalize groups A and B?
