Gotta love these "the sky is falling" posts. Its a wonder the righty tighties here can type out their foreboding mind prattle waving a CBO report in the air to bolster their belief in doom and gloom scenarios.
For one thing even with all the king's horses and all the king's men the CBO has a dismal record for accuracy with long term projections. It would be just as useful to use Walter Mercado, Theresa Caputo or Ouija Board. If it where as good as people seem to think... seems to me we could have avoided the entire global crash of 2007.
For another thing... no one knows what will happen in 25 years.
We do know from past experience a couple of things that increased the size of the middle class.
1 pandemics that wiped out huge swaths of the population increasing the bargaining power of a work force.
2. Socialism or something similar...
Either way the uber wealthy always have to give it up.... either willingly or by force.
The French Revolution, The Russian Revolution, Chinese Revolution all had devastating impacts on their nation's economy and all grew out of income disparity.
We know too from historical records that when the majority a nations money becomes concentrated among a small percentage of its population it always collapses from within and succumbs to rebellion.
