You're most likely 100% correct either the issuer (government) will find a way to abuse it or the receiver will, but if even 1 - 10% of people can be given the push to get themselves out of poverty over what's currently available then I think it's worth trying. We're never going to solve these issues with one change.

We have to make one, see how it works and then fix from there but just sitting around debating the pros and cons and never doing anything has never helped anyone. Which is basically how its been here.

We're so busy arguing over the best solution that nothing is ever done.
