Is that why?
I thought it was because capitalists hate competition so they buy politicians to keep antitrust laws weak and then buy and shudder the competition so consumers have no choice but to buy from them.
How many airlines exist in the USA?
How many national grocers?
How many national retail chains?
How many tobacco manufacturers?
There’s plenty of market share, there’s just too much greed to share the market.
Consumer choice is an illusion.
It sort of depends on the capitalist. Some prefer competition because it sharpens their skills and they learn from other players. Insights you can appropriate can be very useful.
Others want an advantage, are willing to pay for it, and politicians, regardless of political affiliation, act like there's no such thing as a bad monopoly.
As my late Uncle Cas, the one who founded his own oil company, told me when I was but a young sprout, "Washington is a marble halled whorehouse. Every one of them can be bought and sold if the price is right."
Still...
Consumer choice isn't completely an illusion...
yet.
