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 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!
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.
Not really. Let me tell you of a personal insight I was able to gather from starting as a poor kid, to a middle class, and to an upper class (I guess) person.
First off, the mindset when you're poor isn't how to make money to make more money, it's to make money in order to make ends meet. Which is why people that employ lower classes could get away with paying them stupendously low fees. They are at the mercy of these people considering that the slightest sign of rebellion is going to leave their families' stomachs empty.
When you become a middle class person, you've basically risen above the fear of losing finance for your basic needs, so now what you're looking for is to make more money in order to meet other needs. Adventure, luxury, other stuff that doesn't necessarily equate to being important but is definitely something that shines bright for a middle class individual. This is also the reason why they oftentimes find themselves losing their status, cause from all those spending, they didn't bother looking if whether they can save some of it in times of need, or to keep a consistent profit stream for when times get rough. They basically live in the "now"
Finally, the rich. The rich doesn't bother over stuff that the poor and the middle class would normally wrack their brains over, they can do it anytime they want anyway, so they focus on the main thing that would enable them to do this things: Money. Rich people will be seen working for money, and making money work for them, they seldom go to adventures and trips, and makes sure that their main investment, the body and the mind, is in tip-top shape. This is why you'd see rich people ripped and eloquent and smart, they got there for a reason, and they are staying in their lane because they have the capabilities.
Instant cash is something that both the poor and the middle class know is impossible, that's why they don't push for it. The rich knows it's improbable, so they make ways and do things that would allow them to do it.
