I've noticed this in my own life and in the lives of others quite strongly as of late. It seems that our total *real wealth*, those things that we value as human beings, are limited by the utter utopian daily allotment of time.
We can be spiritually rich, but that leaves us very little time to pay attention to the material needs of our families and ourselves. Or we can be materially rich, and that leaves us very little time to pay attention to any abstract studies of philosophy and theology.
At first glance, the clergy seem to have defeated this- but in Catholicism, what has really happened is that the clergy are spiritually rich and materially very very poor. I wonder what the salary of a Bishop is? I know your average parish priest earns about $12,000/year- below the poverty level for a single person. Every time I hear somebody speak against the vow of celibacy, I wonder if they know how materially poor the clergy really is.
