"If that is so, then why is it considered news when workers buy their place of business?"

Because it's a crowd-pleaser of a story, and it's different from the normal case -- that being that most of the time a corporation's "workers" own their piece of the corporation by owning stock in it.

That's an idea, incidentally, that is proving to be not such a great idea -- not because it shouldn't be done -- I like it -- but because it is often the only stock a person owns and that lack of diversification can be very bad. Also, many corporations are run by moral reprobates (like the leaders of our country) who don't bat an eye to steal their worker's earned pensions and give themselves bonuses with the booty. That's not the rule, but when it happens (like United Airlines) it sure makes for a juicy news story.
