If you want to see the result of wealth redistribution, go check it out yourself. You'll meet young men and women in the prime of their lives who spend their entire day in a coffee shop and later a bar, sipping a beverage discussing art, culture, poetry, how business - all business exploits the proletariat, and how government owes them even more than the roughly $25K per year they get for doing nothing. Then go talk to the entrepreneurs in the same district and learn where those wages originate and what it costs business both in taxes and their ability to find and retain staff.
I can assure you that the restful classes are alive and well and are waiting for this idea to take root and flower into contempt for innovation, entrepreneurship and hard work with a massive drain on those who do contribute.
Can you give more details? What are rates of childhood malnutrition like? How hard is it for the sub-middle-class (or, God forbid, the unemployed) to get medical care?

Underlying your position is the assumption that society can properly arbitrate what is "unproductive rent-seeking" versus "socially destructive entitlement culture."

If you think that you can get that amount of money from doing nothing in France, you must have spent that year on crack. Do you have any idea how the french welfare state works? The minimum income (if you're eligible) is currently about €6000 per year. And that's not even enough to pay rent in most french cities (I'm paying €700/m for a 35 m², one bedroom, apartment in one of the poorest suburbs of Paris).
