Material Solutions are Inadequate When Talking About People...

This is off-topic for an article I'm attempting to work on, but I stumbled upon this quote and was struck by it once again, not so much because of what it says about Marxism, but because of what it says about people and their needs:

Marx not only omitted to work out how this new world would be organized - which should, of course, have been unnecessary. His silence on this matter follows logically from his chosen approach. His error lay deeper. He forgot that man always remains man. He forgot man and he forgot man's freedom. He forgot that freedom always remains also freedom for evil. He thought that once the economy had been put right, everything would automatically be put right. His real error is materialism: man, in fact, is not merely the product of economic conditions, and it is not possible to redeem him purely from the outside by creating a favorable economic environment. (Spe Salvi, Pope Benedict XVI)
