Karl Marx and Zen

Random thought that I felt the need to write down:

Karl Marx claimed that capitalism takes the fun out of working. His thesis was that while working is healthy and natural, working without any emotional investment in exchange for money is just like having sex without emotional investment in exchange for money, i.e. it is a form of spiritual prostitution, making such work a harmful thing rather than a healthy thing.

There is a Zen saying, "Before enlightenment: Chop wood, carry water. After enlightenment: Chop wood, carry water."

What if the key part of Marx's criticism isn't "for money", but rather "without emotional investment"? What if the biggest problem of capitalism is not that some are rich and others are poor, but rather that a lot of people don't have any sort of relation to the work they do?
