You are not poorer because somebody else is richer. If you think so then it is just your greed and envy talking.
Uh, no, not really. The fact is, the labor I produce has value. I keep a running spreadsheet of innovations I've come up with in my job and how much they've saved the company I work for. It's well over $480,000. And that's just the innovations and savings, not the value of the mundane parts of my job.
So where did that money I created go? To investors. The stock in my company increased from a bottom value of $19.00 a share at the low point in the recession to a high of about $235 now.
This is the problem with an investor economy rather than a labor economy.
Or as a wise man said once...
"Labor is prior to, and independent of, capital. Capital is only the fruit of labor, and could never have existed if labor had not first existed. Labor is the superior of capital, and deserves much the higher consideration." -Abraham Lincoln
