Yes, you are privileged, and your totally baseless comment that "most people" won't work for a decent living shows that you have entirely the wrong attitude about it. I also have a pool, a bit bigger than yours in fact, and I'm privileged too. Acknowledging one's privilege has no shame.
You could have made your point about heat sans the sanctimony and braggadocio. As homeowners, you and I choose a lifestyle that requires outdoor maintenance in some pretty appalling conditions.

It's extremely tasteless to call names and cast aspersions.

Like 95% of people on this board, I detest this weather. Just important to keep some perspective and realize that none of us is particularly special.
