difficult and elusive. Perhaps an insight into what I call the "organic" nature of this problem ('Gap') is another section from Fareed Zakaria's book...
"Peter Thiel, the provocative tech entrepreneur and investor, admits with startling honesty that "competition is for losers." The goal of every company, he notes, should be to create a monopoly. In the tech world, the winners have succeeded beyond any historical standard"...there are lots of "imputations" to this line of thinking, directly affecting the Income/Wealth Gap.
To this I would add that to varying degrees, all companies harbor such desires and with this "ethos" we can expect ever greater rewards for the "winners" and ever smaller compensations for those lower down in the enterprise that do their level best to just hold onto their positions.
While I've personally seen and experienced a corporate environment that largely obviates the need for government intervention (i.e. tax reform), it is highly unlikely that resolution can be found without it. I'll expand on that experience in a subsequent thread.
