That's literally it. They equate it with sin. The sin of sloth. Not that they think in those terms (filthy Protestant heretics, the lot of them) but it's taboo because they think of it as stealing, because they don't see the whole picture, because it's been deliberately obscured from them their entire lives. If they were to understand just how much was being stolen from them every time they go to work, they'd know who to direct their anger at.
Because it's a sin.

Being poor, needing welfare etc. has been characterized as a moral failing, so people think this way.
"Why would I need welfare? I am NOT lazy, I am a GOOD person."
