Monopolies are granted by governments. The free market has a natural solution to monopolies, it's called competition - startups. Big Cos will always lobby governments to add rules and regulation to raise the barrier of entry on their market and thus reduce competition. They, in fact, buy their monopoly from the government.

It wasn't an "lack of power" that resulted in the structure that we now see in both countries -- they are the intended products of explicit gov't policies.
