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.
I can only agree with that. Each of us has certainly noticed these differences at some point. Except maybe the super rich, who walk through life blindly and are not interested in other people.
The poor and middle class aren't trying hard to become rich, because their mind are mostly want to earn a lot money via instant which actually impossible! majority of the people this group are spent their money to buy branded stuffs in order to get respected by many peoples. Do you know which one is selling the branded stuffs? it's the upper class!
Unfortunately, this statement is also true. The chances of getting rich quick are really slim. Sometimes you can make it, with a lot of work or with a lot of luck. But still only a few make it. Most make just enough money to survive but never get rich.
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.
Unfortunately, this has always been the case in human history. The rich get richer and most of the poor stay poor. In order to change this system, much of our planet had to be changed and I don't think it will ever happen. Before that, it can happen sooner that humanity dies out than this system will change.
