You can't make people happy by law. If you said to a bunch of average people two hundred years ago Would you be happy in a world where medical care is widely available, houses are clean, the world's music and sights and foods can be brought into your home at small cost, traveling even 100 miles is easy, childbirth is generally not fatal to mother or child, you don't have to die of dental abcesses and you don't have to do what the squire tells you they'd think you were talking about the New Jerusalem and say 'yes'.
