The biggest trend in administrative law over the last few decades has been reductions in the degree to which the government micro-manages the economy. In both the U.S. (with bi-partisan support) and the EU, industries have been privatized, invasive regulatory regimes have been replaced with light-touch ones, etc. Germany energy law post-1998, for example, is pretty recognizable to someone familiar with American energy law. There was a time when the government either owned major industries, or micro-managed things like the routes airlines or trucking companies ran and the prices they charged. Pretty much the whole developed world has agreed to get rid of most of that.
By and large, these reforms have been overwhelmingly successful. In the U.S. and EU, you can go almost anywhere and get a 4G mobile wireless connection, using networks built almost entirely with private money. UPS and FedEx--and services like Amazon built on them--are the direct outgrowth of the deregulation of air freight. Consumer airline ticket prices are a fraction of what they were a few decades ago (even though airline technology has evolved very little in that time!).
If you look at hiccups like wireless data caps or airline seats getting smaller as signs that deregulation has "failed," frankly you're off the reservation. Just look at areas of the economy that haven't been subject to deregulation. Some of the worst environmental effects are caused by public water utilities, which have for decades failed to make investments to improve their infrastructure. In most places, public water utilities freely dump untreated sewage into rivers when obsolete combined sewer/rainwater systems overflow, they poison kids by pumping water through ancient lead pipes, etc.
Re-regulation and nationalization is on peoples' tongues here in the U.S., but I'd suggest looking over the pond to see what they're doing. How did Sweden wire up its country with fiber? It wasn't through massive government investment, or by forcing private companies into the charity business through universal service obligations. Stockholm empowered to municipal operator to lay dark fiber, with no government subsidies and no mandate to cover any particular portion of the population: https://www.stokab.se/Documents/Stockholms%20Stokab%20-%20A%.... The network was built out not based on "public interest" considerations or trying to fight urban poverty, but simply by building in a demand-driven basis to high-value customers first.
And unlike the U.S., Sweden didn't wire up rural areas by forcing private operators to subsidize rural customers. Instead, it simply gave rural residents a 50% tax break on the cost of hooking up their own fiber: http://www.ftthcouncil.eu/documents/Opinions/2013/Rural_FTTH....
