Hmmm... at one time I only owned less than 100 items. I moved to Catalina in 1969 with a backpack and two boxes. I adhered to the philosophy of voluntary simplicity in those days (besides, I didn't get paid enough to buy much more!). Unfortunately over the last 40 years I've accumulated too much.
For example, I have hundreds of CDs and even 50-60 LPs. Once I get them all converted to iPod format, I can sell them off and eliminate that much "stuff..." maybe even the four CD players I own.
As for "slave labor," I'm not 100% certain of what you mean. If you refer to young children working in factories to help support their families, we did something that altogether different in our earlier history when children were "forced" to work on the family farm. Low wages? $5US per day in some countries is considered to be good pay. There are cultural differences that must be considered. However, if someone is being held captive against their will and forced to work, that I agree with.
