There is always someone looking for a free ride. If access to that ride is made too easy, then the number of people interested in taking it rises. That's human nature and any system that doesn't take human nature into account will ultimately fail of its own weight.

Welfare systems were originally meant as a short term bridge for people who had experienced bad luck to get back on their feet. That is a laudable goal which I support. It's when the bridge becomes a lifestyle that the long term viability of the system comes into doubt. The moneys spent on welfare would be much better served if they were spent on infrastructure improvements and such. That would create jobs and income for those willing to work. For those not willing to work and who don't have a real (not pretend) disability - screw em.
