Do not intervene
Yes, do intervene
1) The cause is from love of materialism and unfettered corporate access to political influence. Also a lack of foresight as seeing employees as the most valuable assets.
2) Long term trend will be a continuing separation of social classes and shrinking middle, until the rich can't isolate themselves from the effects of the weakened masses and start to feed off each other.
3) Solution. Pray. Or identify the problems and make efforts to slowly trend away from them.

Our interventions have been the problem, the last thing we need to do is make matters worse doing more. The "War on Poverty" has been a failure with so much cost to show for that failure, and between ole (D) and (R) they have done enough damage with trade policy, outdated immigration policy, economic policy, fiscal policy and Fed monetary policy.

Can't we just turn Congress off and then turn it back on again?
