I wonder how selectively Noel Gallagher is being reported. The headline certainly doesn't match the text.
I think what he actually meant is that in the Eighties there was still some hope left, in-spite of Thatcher. Some people, like him, who were condemned by the Tories to a life on the dole were less apathetic than now and were motivated to go off do something and "great art was made". Thirty years later, their children are even more downtrodden and have had the motivation beaten out of them.
The government we have now is far more extreme than then and I don't believe that even the most cynical on the Left foresaw just how devastating the consequences of Thatcherism would be. Then there was a Labour opposition who offered a real alternative, now we have a Labour party which has accepted most of the changes which Thatcher introduced - so of course there's less hope around now. In that sense I agree with Gallagher, the Eighties were less shit than now.
I got the feeling reading that to, I reckon Noel Gallagher has been "Clarksoned" to an extent. The culture, society and age of the 80's is quite different to now and I think there is just a sense of helplessness in many young people today. At least in the 80's music was a popular outlet for that which sold bucketloads of singles and albums and with the likes of TOTP and the Tube you could make your performance stand out.
I do know in an interview Noel Gallagher did say that he moved to London because there were too many people he knew in the local pub he visited and if brought a round of drinks for everyone there he was deemed a flash bastard. If he got drinks just for himself and whoever he was with at the time he got called a scrooge for not treating there. He couldn't win and so moved away.
I've never hard either of the Gallagers had anything much positive to say about Thatcher, got this from wikipedia...
In an interview in 2007 when asked about politics he said, "I'd been unemployed all my life. It was a big deal for me when he [Tony Blair] got in. Now David Cameron is no different than our Tony Blair and Gordon Brown is no different than our David Cameron. They're all cut from the same cloth and it annoys me that the biggest political icon in the last 30 years has been Margaret Thatcher, and she's a dick. Someone who tried to destroy the working class. It freaks me out. So I don't really think there's anything left to vote for. I believe that I, as a person, can only change things once every 5 years and that's by voting, and my point is that even casting that vote means that the same guy gets in, the only difference is one has a red tie and the other has a blue one. That's all it means, so I think that I should start the Gallagher Party."
