so Mark, based on your assumptions (to which I somewhat agree) why did we, a country of 320 million people allow ourselves to get to this point ?
There are a few reasons driving this. We have unrest because of automation. This was exacerbated by recession in 2009 when corporations cut back further, employees worked on average more hours with less job security and benefits than before. Unfortunately that trend was already happening, but it became more obvious to many.
Then we have shock jocks. I'll use Rush Limbaugh as an example since he was very prominent. Others were also praying on this anger and unrest and fueled more anger and unrest typically by blaming others and pointing fingers at individuals.
That anger was being channeled on both sides. You had some people blaming "the takers" and targeting ethnic groups and poor people and on the other side you had people blaming the top 1% with "Occupy Wall Street" etc...
One side said we are taxing these "job creators" too much and blamed giving too much to "the takers" for our hardships. The other side blamed the rich for being greedy and for scamming the rest of the country.
Both ideas hit a nerve with people and had statistics that "seem" to prove each side had high moral ground to stand on. Unfortunately people are emotional beings and you can find enough examples however statistically insignificant of just about anything to prove a point and outrage people. I'm not saying that we don't need immigration reform or reform on Wall Street.
However neither of these views is remotely close to the truth and masses of people are being manipulated by others who want to be in power.
So we get to where we are today. We the people have proven very easy to manipulate and the those who want control understand exactly what resonates with us and how to divide us and get us riled up and they use tactics that seem closer to psychological warfare distract us and gain support.
The trends in automation, globalization, and the consolidation of wealth, power and intellect won't be stopped by a president. These trends have been in place for many decades now. Unfortunately there are real problems to deal with. We have an very isolated "ruling class" that grow up segregated from how most of the country live. They don't understand why people can't just work hard and become rich because they see everyone around them succeeding. We have blue and white collar job automation happening at an exponential rate. Each year twice as many robots are put in place than the previous year affecting blue collar work and soon lots of minimum wage service positions. In addition white collar workers are being automated very quickly by computers. Manufacturing is coming back to the US very steadily, but there are not many jobs associated with it. Amazon puts in HUGE data centers that look massive, but once the buildings are in place there are only a handful of jobs created permanently.
What can a president do in the face of this? Nothing. People don't like change and aren't ready to deal with what is coming, yet. So a candidate running for office points to the problems and claims they can fix those problems and uses whatever works to manipulate the voters.
We are in a painful transitional period. The old rules aren't going to work anymore, but people haven't figured out what the new rules are.
Our current economic and social system is broken, but it is all we have to tide us over. Which means that we have a chunk of the population stuck in a poverty cycle, a shrinking middle class and a ruling class with more power and wealth than ever. Historically this is when a revolution would occur, but the drivers behind this are not the same as they have been historically. People are not being used as slave labor. They are simply not needed in the workforce anymore and we don't have a provision for that yet.
As time goes on this will become obvious and society will finally come to this realization and politicians will be able to talk about it. Until that time they will continue to promise to bring back jobs and bring back things that and keep us distracted while they work in the interest of large corporations and the wealthy people who support them.
