True, what's particularly unfair about it is that the companies tend to use proceeds from an industry in which they have a monopoly to fund their price war in other industries where they don't yet have a monopoly. The strategy seems to be to monopolise each industry one after another, using the proceeds of the previously captured monopoly to capture the next one.

If this keeps going, eventually we're going to end up with one giant mega-corporation which owns everything. There will be no more government to protect citizens; everyone will work for that company and it will be the most unfair class system imaginable.

This is bang on.
