I didn't read that in anything j1979 said!?! Just that people who are working full-time should be able to afford to keep a roof over their head, food in their mouths and have access to free healthcare, etc, and if that means that people who earn far, far more than any human needs pay a little more tax then so be it.
You make a vast oversight when you talk of people "dithering around in menial jobs".... not everyone has the aptitude/psychological makeup/personality traits required to do anything other than a menial job. In my opinon that doesn't mean they should be destined to a bleak existence though, surely we are at a level of civilisation where "law of the jungle" attitudes are a thing of the past?
