I think that it is human nature to be competitive because everybody wants to be at the top, to control others. So the issue of class has always been there. Those at the top will do anything, even it it's evil to remain there, because they control the wealth of their society, they will make sure that it is not evenly distributed. This top or high class individuals will go as far as putting their loyalists at the head of government, just to protect their wealth.
I also see something that is very reasonable in cases like this because it already talks about a person's ability to do so in order to maintain his throne of wealth and power through several channels, including through the economy. So it's only natural that there will always be competition in high-class society so that the losers and the winners will always be seen and some of them will never give up to stay rich and be number one globally.
Government can not do much to bridge the gap between the rich and poor, especially in capitalist countries, where the industrialists and the super rich controls the economy. They will always have the upper hand in wealth distribution.
If examined in depth, actually this kind of thing is not included in the government's duties even though it occurs within a country. Because the task of the government is to supervise, guide and also build what is needed by the community so that the rich and poor are only colors in society because it occurs based on the benchmark of the number of valuable assets owned by everyone. So it will be difficult for the government to intervene in such a problem because there really won't be a common ground to resolve.
