RE: Bubbles Eating The Middle Class
Middle class was created for a reason and i assume that reason was to provide a good educated labor that will work morning to evening and keep the wheels in motion.
They were given the illusion that they are better than the poorer and if they work hard they can be part of rich family but they were never told that they have to come out of their comfort zone and do something different/extra than 9 to 5 job.
9 to 5 job is for daily survival not for the wealth creation. You always need that extra source that you do not rely on for day to day needs and this additional source become the source of funds that you can invest and make wealth.
