An old MBAer here, and a fervent believer in capitalism.
Now as an ancient MBAer, I believe more in the free market.
Too much of our capitalism today is based on lobbying and bs like that versus the seeking efficiency and research as you noted.
As Trump drains the DC swamp, we will be amazed about the dealings that large to main street business has bought/paid for from illegal workers to laws or treatie or whatever could be bought for their businesses.
That is why Bill Clinton was so popular with industry leaders to again so called main street businesses. He was available for a price and could be bought for some sweet quid pro quo!
Of course neither system gets run properly because we have so much government interference. Of course even then, if you think about it legislative capture is a form of efficiency, the companies that lobby best find clearer running.
I’m not sure how much Trump can really effect this. Sure fed-zilla is a major obstacle, but every city, county and state has their own grouping of palms that must be greased. Especially for brick and mortar retail, how much you pay for land is so dependent on how much the local government likes you.
