"Socialism!"
Socialism not required. Pretty much everyone in the US has access to electricity and the telephone, which was brought about without state ownership of the companies providing the services. Government incentives may well have a place, but that does not need to reach the level of government ownership or control.
In Britain, we had actual socialism in the telephone service and abandoned it. This was a good thing, although British Telecom still displays some of the faults of a monopoly state supplier, as it hasn't been properly broken up in the way that the commercial giant AT&T was in the USA.
The government can add funding or tax incentives for social purposes without taking control. They do it all the time, even in capitalist countries, This route is probably less efficient than leaving capitalism alone. In Britain, we over-regulate, so that service providers fear that any investment they make will be negated by new rules after the fact. Why put money into infrastructure when the bureaucrats are poised to snatch your evil profits from you as soon as it is finished?
