Osborne promising full employment? Oh, fuck off! The Tories need a pool of unemployed to keep people scared of losing their jobs to somebody who’ll take less, thus keeping down wages and riding roughshod over worker’s rights.
Hitler promised Germany the same; how did he go about it? He put those he didn’t like (anybody who wasn’t a Nazi) into work camps or death camps.
How did he pay for it? Through war and invasion.
