Beggars (real or fake, unshod or shod, it doesn't matter) are necessary for society: they provide the possibility for everybody else to feel good: I give something to a person who asks for it. Afterwards I feel good because I can think of myself as someone generous who just did a good action. Only the act of giving is real: the thinking about having done a good action happens only in my head but provides good feelings nevertheless. The thinking about the beggar being real or fake, deserving money or not, also happens only in my head, but the feelings caused by these kind of thoughts are definitely not as good: the generous feeling is replaced by some kind of aversion feeling.
What do I want to feel?
