'According to you, people are stupid enough to be tricked by the global elite for decades'
Some people are, many aren't. Some people break out in cold sweats and panic attacks at one of their scary adverts about the planet being submerged under water or alternatively turned into a desert where nothing grows, but many people say "they're at it again, up to their usual scaremongering tricks about the apocalypse".
"bright enough to say 'hey, this Trump guy really understands me and is 100% going to fight for me"
Absolutely, confounding all of the expectations of the Republican elite.
'People voted for Blair too, you know. In quite big numbers. They were stupid then, but not when they voted for Farage? '
Yes, I voted for Blair in 1997 but soon realised I had been conned and later voted Farage and was only conned by our out-of-date unrepresentative First Past the Post electoral system which granted 4 million voters, one solitary parliamentary seat.
'A lot easier for either business 'barons' or governments to control than, you know, the sun'
They can't stop China developing and exploring for oil short of going to war over it. Without international binding climate agreements and treaties there is nothing they can do to stop human industrial progress and oil exploration. There is nothing they can do to lower worldwide progress and increasing living standards.
'So, which model has the shadowy global elite chosen?'
I don't know because I haven't been keeping up-to-date with all their shenanigans, but rest assured, the one they will choose will be the one that is financially most advantageous to them and financially least advantageous to the taxpayer, and there will possibly be what they call a "charidee", receiving taxpayer fundied grants, involved at some stage.
