Christianity is like a health insurance risk pool. In a health insurance risk pool the healthy people have to join to balance out the sick people so the premiums don’t skyrocket. In Christianity the people on top (who have the least incentive to be virtuous) have to be as virtuous as the people on the bottom or the system collapses (as it is doing now before our eyes). It’s harder to be virtuous when you are on top because you have power and it becomes completely optional and is even detrimental in your quest for more power and control.
Christianity romanticizes things where the weak defer to the strong like forgiving, waiting and serving. But the strong are supposed to be doing these things as well. If they don’t the system breaks down. Especially because those at the top set the tone for those further down. People imitate successful people.
