I tend to approach something that proclaims to be the "truth" with suspicion. The interesting point for me being the duality of views about Labor Day. The duality of views extends to other topics. For example, the President announced an address to students on what is the first day of school for many and there is something of an uproar about this address. As previous Presidents did similar addresses, there like was something of a similar uproar. If there wasn't, then that would be a story.
What ever you do with your Labor Day, please enjoy it.
