As a result, the poor and even middle class have to jump over one real barrier, their lack of funds, and more importantly, like the Elephant that learns young that he cannot break the chains and never tries again
Its a lifelong process to overcome that 'barrier'. Imagine taking a small leap at the time, you will eventually get to the higher steps. Even if you cant overcome that 'barrier' atleast your offspring wouldnt have to start over again. The 'barrier' is actually not limited to economy factor but most of the time, economy factor will define the next steps for the middle class
The mentality of the people that belongs to different economic classes really varies.
If you are not from the higher economy class then you would have alot of concern regarding money most of the time but even if you came from a high economy class, you might have concern about making alot more as well
