Love of Money, Gini Ratio v.02

If you look at the research done about relationship of crime and the Gini Ratio, Gini Ratio being the rate of income inequality within a region, it is positively correlated. So if there were a lot of disparities in income, crime rate is higher, equal amounts of income, lower. 

On one hand you want to reward the people who have performed well, on the other hand you also want to keep the crimes low. Some people, a religion in particular proposed a solution that people shouldn't show off their wealth. This has a strong reasoning, however it is kind of sad and demeaning of humanity how people are so unable to deal with this, it is a bad thing to be luxurious ever once in a while (but it seems to me that it is the Truth). 

The Love of Money is the root of all evil, Jesus said. And it goes both ways, the service receptor loved money so much they refused to reward, the service provider loved money so much they refused to cease from being bitter about not getting the amounts they expected to get.

We, the Asian Oriental community, tend to point fingers at people who negotiate and asking for more money, people who are dissatisfied with their rewards. And this is also a working solution. Lower the expectations, and so, lower the evil. 

Is there a way, or is there an empirically accurate way of setting the standard on the rewards? Too many factors to consider different point of views are all relevant. The rarity, the sustainability of the benefits, the strategical positioning of the solutions, the hard work put, the damages or consequences of having the problem not solved otherwise... 

Look, I hate the fact that actually I'm the problem here... I'm the one who breed dissatisfaction among some people about the rewards they deserve. 

But really, putting the expectation down is the solution instead of actually rewarding them?  

To continue the previous 2 paragraphs:

The state of the environment, I mean to illustrate, when the COVID outbreak is rampant, it is not reasonable to set high expectations... a lot of point of views are relevant and that's why individual negotiations instead of centralized price fixing is encouraged. 

But damn, if we solve this problem... everything will definitely be much better. This is the next singularity
