It's funny how the cranks can come out of the hiding during a crisis and spew all kinds of nonsense. Stuff like this. Yes the abolishment of the public vacation on may 1st might increase revenue, but abolishing public holidays won't rescue countries. More so the new revenue would only be wasted by politicians. And the people would lose something more precious: private time; not necessarily for leisure.
I think it is this kind of stupid demagoguery that paints economists and business consultants in a bad picture.
