I pose a question for you today:
If you're "middle class" in America, but you live better than 90% of the people on the planet, is the term "middle class" accurate?
To wit, say you're living in a $200,000.00 house out in a former corn field with a bunch of other suburbanites, you travel the 1/2 hour in to your job in the city each day with all the other travelers, your house is what? 3,000 square feet, it has a lawn sprinkler system, it's either brand new or looks it, the household income is, again, what? $125,000.00 to $150,000.00 per year (I'm trying to shoot low here and stay well under that magic $200,000.00/year range), you go on regular, dependable vacations, you have a late-model automobile, etc., etc.
You get the picture, I think.
This, in America, is considered solidly "middle class". There are lots of people for whom this is an accurate description of their social and financial status.
And, again, it's WAY over 80% of America's population, in terms of wealth and status and, I believe, much more than 90% of the world's population's status and financial situation.
So could we stop kidding ourselves, just to feel good?
It's decidedly NOT "middle class."
