Without an economy, you can't help anyone. Britain has Thatcher to thank that it isn't Greece right now.
Attlee would have been as useless as Wilson at dealing with the problems Thatcher was forced to confront.
Attlee has the luxury of being a Prime Minister who was required to do things that were popular. Thatcher was required to do things that were unpopular. Nonetheless she did them, and did them exceedingly well. Millions of Britons who have ultimately benefited from it continue to curse her, ignorant of how lucky they are.
She's basically Batman.
You can't just 'assume' though- that's like saying what if Thatcher came to power in 1945, or if she came to power in 1997 when there actually was an economic boom- would she have done different things. Attlee's administration created the NHS and that will always be one of the greatest successes in UK history, and certainly something in his favour.
At the end of the day we're not gonna agree- you obviously have a lot of connections with the UK even if you are Australian (I think) but if you know all about Liverpool/Merseyside and what it was like under her, you would understand why she is loathed in these parts. Her and Geoffrey Howe discussed a 'managed decline' of the entire city before Michael Heseltine's intervention, and her establishment covered up the police's role in Hillsborough.
