Efforts by workers to better themselves Teribus? They were called Trade Unions. They brought people together, gave them a community identity beyond their own selfishness and race group, educated people about history and politics, showed them how their interests differed from those of the rich..... no wonder she wanted to destroy them, and sad that she succeeded. The result was New Labour.
I'll say this for her though- she wouldn't have given in to the fuel tax pickets if she'd decided on that policy- she wasn't a coward like Blair. She was a bastard and a wrecker, but she had courage. So, of course, did the SS, suicide bombers, and kamikaze pilots.
