After some machinations in the owning family, it faced being sold up to powers of finance capital -- sold on Wall Street. Family members would get a huge payday. The new management would eventually required by its Wall Street investors to run the company like every other supermarket chain. Lower wages, lower benefits etc. etc.

The more that the productive wealth of the country is controlled on Wall Street, the behavior of individual companies will directed toward maximizing short term profits, in order that the company is an attractive investment on Wall Street. The success of a grocery chain depends on being more profitable than any other form of investment: resort chains in the tropics, gun manufacturers, medical marijuana distributors. It will not survive simply because it is a profitable and successful grocery store that gets groceries into the hands of people who need them at a fair market price.
The employees of Market Basket and the citizens of New England communities fought to keep the ownership and control of Market Basket local. They won. Good on them.
