Trump is nominating some people with tremendous business experiences; but running a country isn't the same as running a business.
Trump and Tillerson have 40-50 years of management experience. Top management guides, they don't "run."
During my corporate career, I worked with senior executives. We had board members, that included a former Sec. of Defense, and a former Deputy Sec. of Defense.
Government is highly screwed up. Workers create unnecessary complication, partly to make themselves important and necessary.
Private industry people can cut through a lot of government BS. I hope they do so.
Our corporate senior vice resident, that served as project manager for the Alaska Pipeline had a philosophy of management:
"What are we doing, why are we doing it, when are we going to stop?"
If it turns out that Trump and Tillerson cut some dead weight and overhead from our bloated bureaucracies, it will be fabulous.
