It is true that so far as wealth gives time for ideal ends and exercise to ideal energies, wealth is better than poverty and ought to be chosen. But wealth does this only in a portion of the actual cases. Elsewhere the desire to gain wealth and fear to lose it are our chief breeders of cowardice and propagators of corruption. There are thousands of conjunctures in which a wealth-bound man must be a slave, whilst a man for whom poverty has no terrors becomes a freeman. (William James, The Varieties of Religious Experience, p256)
I have long noted, being a tax preparer and working around wealthy people and all of that, that wealth, once accumulated, takes on a life of its own and soon becomes master, rather than servant, of the person owning it.
