@Daniel B.
While I agree with your sentiments, I disagree with your assessment that Capitalism isn't working. Most properly run capitalism *IS* working !! It is only rampant mad-dog American-style capitalism that isn't working.
There are millions of companies that are owned by families or groups of friends and have only sold or disposed of a minor part of their capital in the open market. These companies are rather harder to "takeover", hostile or otherwise without a very, very good offer. If there is one, the shareholders cry all the way to the bank !!
American-style capitalism is where the majority of the shares are sold and the founders pocket the proceeds of the sale but still keep the management of the company and run it as though they still own all of it. In the event of a hostile takeover, the side with the most votes (directly owned or persuaded/coerced into supporting them) will win the fight handily; unless the relevant government steps in and declares that the sale was against national interest. This is known as protectionism. America, the self-proclaimed champion of free trade, is the *MOST* protectionist country in the capitalist world !!
Once a company has been taken over, the new owners do not have any duty to the consumers other than to provide a merchantable product(s), even though the previous owners owe the consumers a debt of honour for believing in them and their company and their product(s).
BTW, if you think a company owes its consumers a metaphysical "debt", then should not the consumers owe the same "debt" to the company and rally round to support it in its time(s) of need, even to the extent of putting their hands into their pockets and stumping out hard cash to save the company ?? A "debt" of care cuts both ways, you know !! When was the last time you tried to save a failing company that made a product that you liked ??
