Gingerbear - your unclouded view is what we're interested in!
Imo Thatcher was an aberration and not of this world. Hated her passionately.
Looking back, I find myself occasionally thinking she had principles (like them or not) upon which she based her decisions so you had an idea of what she was up to. This lot do not have principles and their decisions seem to be based on no guiding principle other than what they think the electorate would go for at the time.
She started the Nanny State, Blair has (almost) perfected it, Brown is continuing it (until perhaps it looks expedient to him not to).
She started the 'me' society based on greed; we now take it for granted. She started the dismantling of the NHS; Blair/Brown continue it.
Thatcher, if she were in power now, might decide to boycott the Olympics; Brown will dither until it's too late, or leave it to each individual team member; as happened some years ago with cricket, where a definite decision needed to be taken, but wasn't and it all got a bit silly, but I can't remember the details.
