Today we have hyper-specialization and if you're in the top 1% of whatever you do you'll have a job for life, and if not you'll be lucky to ever have a job. We're still in transition, but all the trends are there.
We life in a country which has a huge economy, and yet tons of people who are unemployed. And yet, our roads and bridges are falling apart. Just tax a small bit of the wealth flowing through the country and give people part-time jobs fixing potholes or whatever. When we run out of those they can fix bridges, dig trenches for municipal broadband, and so on.
I agree that this appears to be occurring but it is because the top 1% (in all sorts of professions - entertainment and media, mobile startups, finance, etc) are able to use technology to leverage their talents in ways not possible before, in order to reach more and more people. By reaching more people, they are able to make more money.
However, note that the infrastructure that they use is still not free (and probably never will be). The cost of building and maintaining the network needs to be borne by somebody. And a lot of that network building and maintenance is done by guys with hardhats climbing cell phone towers. A lot of the $19 billion valuation of Whats App is due to the hard work of those guys making a basic middle class wage. If Verizon or AT&T wasn't paying them, Whats App would have to, and then Whats App is not a 50 person company, but rather a 50,050 person company.
So the trick is to get the money from the 1% who use the leverage to the 99% who build the tools that the 1% use. Maybe Whats App (Facebook) should be responsible for paying a big bonus to the people who work on the towers. It would surely encourage more young people to become skilled tradesmen who could improve our cellular network. Heaven knows we need more/better cell towers more than we need another app writing software firm.
