Time is money they say & I think someone didn’t want to go to the effort of dealing with these household furnishings. Sending it to the dump would be fast and easy.
It seems like such a waste though.
Personally I think money could have been saved, or even gained if some creative thought had been given to this situation, resulting in a better outcome.
There is a low-income mobile home park across the street. A “FREE” pile on the curb would surely have taken little effort and could have blessed others.
Other options include:
Craig’s list, where the things could have been offered for sale or for given away. http://www.craigslist.org/about/sites
Freecycle is another option http://www.freecycle.org/
Thrift stores are always looking for donations. A phone call is all it takes to schedule a pick-up.
To give the benefit of the doubt to this dumpster’s filler maybe it was full of true junk.
