There will always be a few who take advantage of this, and yet if they are this kind of person who will fiddle a system for their own gain, who would want them working for them? Perhaps it is better to let them stay on benefits and out of harms way than in some sensitive, vital or otherwise important work. Maybe it's better to let them take the easy road, save time, money and face in the long run. If they're going to go to such great extents to fake some kind of health condition in order to not work, imagine what kind of quality productivity they'll have when forced to work? Zero. Leave them to it.
Sure, it's not a nice feeling when we must rely on support but don't let the pale faced, common perception blind politicians tell you how to feel. They'll sign cheques for millions every day when it comes to lubricating the wheels of power, but when it comes to serving the people who voted them in, who's family worked hard to push for rights over generation after generation, just work on yourself. When they laugh in the seats in the house of commons,when they gloat, they're laughing at their own stupidity. The best bit is, they're too stupid to realise.
How do you make a neo-liberal happy? You can't.
You're okay buddy, keep going, don't listen to them.
