Without need to look the studies and statistics, I think everyone know if the wealth gap between the poor and middle class with upper class are extremely far.
...
The upper class already have a lot business, they're also make a lot money from stupid poor and middle class, so it make them can expand their business become bigger and bigger.
this world economy is controlled by some people, that is very true, but aren't your words very harsh toward the poor! until whenever it is true that the gap between the poor and the rich will forever exist, many rich people create new businesses with the aim of getting money from purchases made by the general public, for example > cigarettes, many cigarette business people make money from selling cigarettes to poor people because they are true cigarette addicts.
The solution for equality of wealth distribution will never come from government who are the same people causing the inequality.
No matter how nice a politician or public office holder is, one thing is certain, they wants to clinge to power and make more money.
I just feel there might not be any solution coming to the rescue soon. The powerful sees oppressing the powerless as a fun sport.
Just think about the reasons why so many governments of the world are against cryptocurrency.
the government in many countries is controlled by businessmen because when they carry out campaigns, the political funds they receive can come from them.
because the emergence of bitcoin and cryptocurrency really cannot be stopped, most governments are afraid that what they have controlled so far will just disappear, so they do various ways to define bitcoin and cryptocurrency as a form of resistance against the government and the world economy.
