It's a very interesting idea... Thanks for linking it.
It's a principle I fundamentally believe in: a universal benefit, whereby everyone has a 'flat rate' paid to them which provides a basic living standard, and then they are motivated to get decent jobs by getting to keep what they earn on top.
I've said on MN for many years that one of the biggest problems is the current system we have in that it acts as a disincentive. Some one on benefits starts working, and realises they are hardly any better off as they lose benefits as soon as their wages come in. Others may find that they can drop working hours, and earn overall almost as much working half the week because they get topped up to almost the same as if they work full time. Others may be working hard but have little incentive to go for even higher level jobs with masses of responsibility because they'll be taxed to buggery!
So, in theory this sounds like a great idea.
I'm not sure how certain issues would be solved though... The housing market is a really big one. A universal benefit to provide a basic level of living is NOT going to be the same in London as in Newcastle. Therefore you're already having to apply weightings to try to put people in the UK on an equal footing.
What happens to the people who do fuck up? Ok there may be fewer of them with this system, but there will still be people who piss the money away, spend it on booze, fags, run up debts etc... Do we leave them and their children without food? Or will these people end up getting more money handed to them?
The thing about trying to apply a fair system, is that it assumes that everyone is equal. I'm not talking here about people with disabilities, or illnesses, because clearly there are some people who can't live independently, or need a higher level of income to meet their basic needs if they have mobility issues etc. What i mean is you could take two people with similar levels of intelligence, from a similar educational and social background, and they won't necessarily have the same outcomes, not because one has had better life chances than the other, but simply because people are all different. Some people are prepared to work harder, take more risks, push themselves out of their comfort zone etc.
My other reservation is less clearly defined in my mind, but I have a lurking feeling that this could have an unintended outcome of reducing the role of women in the workplace and society. It would be a retrograde step if fewer women held positions of responsibility.
Overall though, surely it's got to be better than the current system, which just seems to shaft people who try to play by the rules. If you get yourself qualified and trained, and get a decent job, you see people around you who are paid not much less who may be not working at all, or working very part time hours and being topped up. The more hours you work and the higher you rise in the workplace, the more any benefits are stripped so you end up only marginally better off. There is definitely not a big enough differential between those who work and those who don't, in terms of finances.
Alongside that you have couples who remain together being shafted: eg - their adult children aren't allowed full maintenance loans at higher education, whereas a couple can split up and continue earning the same income but their children will be entitled to more loans and bursaries.
It's become a very crazy messed up place economically, this country. Surely it's about time systemic changes were seriously considered.
