living/maintaining your own home without motgage and driving/maintaining a Car already paid for means with 3KUS$ per Month you can live very comfy.
Mid Class?
I don't know if it is "Mid Class", depends what mid class for you means.
here on the Isle Mid Class starts with 2 large SUV's in the Garage, not older than a couple years of course, and Gardener and Maid and Nanny in da House, to maintain such house and vehicles and employees would not be possible with 2-3K per Month, but it is enough to live very comfy in a own small house(a large own house requires also large Maintenance costs of course) and driving a small used Car.

That would be living extremely well in the U.S., but Mike generally gives very good advice. Frankly, I think more highly of most of Mike's guesses than many other peoples' facts....
