    “We have grown literally afraid to be poor. We despise anyone who elects to be poor in order to simplify and save his inner life. If he does not join the general scramble and pant with the money-making street, we deem him spiritless and lacking in ambition.”
    —William James (1842–1910)

    “Human development is a form of chronological unfairness, since late-comers are able to profit by the labors of their predecessors without paying the same price.”
    —Alexander Herzen (1812–1870)
