As I wrote, it depends on many things. I can imagine a situation where this would work; I can also imagine a situation where it would not. As I also wrote, I can imagine such system functioning well if people who don't work get enough money to survive, but people who do work get significantly more.

Data point: In Slovakia many uneducated people don't work, because it wouldn't make economical sense for them. Their wage, minus traveling expenses, would be only a little more, in some cases even less than their welfare. What's the point of spending 8 hours in work if in result you have less money? They cannot get higher wages, because they are uneducated and unskilled; and in Slovakia even educated people get relatively little money. The welfare cannot be lowered, because the voters on the left would not allow it. The social pressure stops working if too many people in the same town are doing this; they provide moral support for each other. We have villages where unemployment is over 80% and people have already accommodated to this; after a decade of such life, even if you offer them a work with a decent wage, they will not take it, because it would mean walking away from their social circle.

This would not happen in a sane society, but it does happen in the real life. Other European countries seem to fare better in this aspect, but I can imagine the same thing happening there in a generation or two. A generation ago most people would probably not predict this situation in Slovakia.

I also can't imagine the social pressure to work on the "generation Facebook". If someone spends most of their day on Facebook or playing online multiplayer games, who exactly is going to socially press them? Their friends? Most of them live the same way. Their parents? The conflict between generations is not the same thing as peer pressure. And the "money without work is a basic human right" meme also does not help.

It could work in a country where the difference between average wage (even for a less educated and less skilled people) is much more than one needs to survive. But it can work long-term only if the amount of "basic human right money" does not grow faster than the average wage. -- OK, finally here is something that can be measured: what is the relative increase in wages vs welfares in western European countries in recent decades; optionally, extrapolate these numbers to estimate how long the system can survive.
