The thing that bothers me about these discussions is that people are going "Oh, no! They might force this on everyone!" but low income people/people who rely on government transfers are already incredibly vulnerable to this sort of control. (Can someone explain the justification of food stamps in the US to me? Everywhere else they just give you money and you decide whether to spend it on food or other things. The explanation I've seen is that it was to help farmers sell food by securing a market.) It seems like it's ok if it only happens to the have-nots but a crisis if it ropes everyone in. I say the opposite: try to rope everyone in and it won't happen. I'm more worried about it being used to target the have-nots while the rest of society goes merrily on its way, exempt and completely oblivious.

Australia until recently had a "cashless welfare card" that quarantined 80% of welfare payments and prevented them being spent on anything that the government deemed unnecessary or being withdrawn as cash. The new government removed it, but there has been a long standing public belief (fueled by the right-wing and Murdoch media) that welfare recipients are "bludgers" and being paid to sit at home and watch TV which has allow successive governments to put in place more regressive controls over how welfare recipients spend their pittance.
