Management are not the dirt bags at the top, follow the money to the dirt bags house high on the hill overlooking cardboard city. If the fruits of labour do not stay in your community and circulate, you have worked for little or nothing. There is no such thing as a free market, there never has been and there never will be. The word "free" indicates capitals freedom to breach borders and tariffs and deregulation and easing all other public interference to free exploitation of both resources and labour. The common goal between lower management and labour is making a living, the dirt bag at the top just wants to make a killing even if the employee has to be chained in bare feet to the forge or chained to the coal truck for sixteen a day.
If you can scale your thinking down to an everyday level for a moment, you might want to consider that if you have a couple of shops making specialty soaps (for a more down to earth example), they are essentially competing against each other - in a free market. Nobody is forced to buy from either one (they have the "freedom" to do that), so that the one that offers better products and/or service at a price the consumer thinks is worth it, wins.
Companies choose their target markets (types and geographic areas) as part of their business plans...very common. All this talking of breaching borders, etc. is pretty extreme...applies to a very small piece of the total picture.
As for the "dirt bag" at the top, I think there are some cases of that for sure, just like those same types of dirt bags exist at the top of some unions. But, the vast majority of business owners don't deserve to be painted with that brush.
And I think chains went out before the horse and buggy disappeared.
