Terry I was referring to the incredible environmental damage done in the name of "socialism" by both the USSR and China. Something China keeps on doing to this day.
They may have a modern transport system, in their special economic zones, but they also have some of the highest levels of pollution in the world. Witness virtually having to shut down commerce to host the Olympics.
I, also, grew up on nationalised (socialist) rail systems. The Labour party in the UK nationalised the railways after WWII. They sucked. People very rapidly forget just how bad those services were once they have a "fat cat" business to blame. I stood from London to Newcastle several times on our wonderful nationalised rail services... I saw quite a lot of long distance rail in the Army, as they issued rail warrants in preference to anything else as it cost them nothing.
The point I was making is that some wonderful utopian "socialist" idea does not mean we're going to solve the problem. We have to target the biggest emitters first and then get to the rest later. Those emitters don't live next to public transport which will take them to work.
In fact, in London, one of the biggest problems are what they call "Chelsea tractors". Otherwise known as Range Rovers and Porsche Cayenne's used for taking the children to school. Tell me, honestly, does London lack public transport? The Tube is electric, almost all rail in and around London is electric and even the new routemaster busses are electric backed by a diesel generator. They drop into electric within seconds of stopping or travelling slowly.
What, in the UK, do we need to do in order to reduce emissions? Get those shiny, expensive, gas guzzling, vehicles off the roads and onto EV.
But let's not do the sensible thing. No, let's spend billions on a fantastically clean Electrical Bus network for London to get rid of all those busses. So they can mess up the traffic for all the Chelsea Tractors. That would be a wonderful "political" solution.
Sorry my sarcasm meter is off the gauge.
When it comes to cleaning up our act on CO2, neither "Socialist" politics nor "Green" politics count. Only less CO2 counts. In the UK we "recycle" glass. We produce 100m tonnes more CO2, recycling the glass, than we would produce if we just made new glass.
Now that is "Green Madness" and "Socialism gone crazy". But it sells well.
