What is this communist nonsense? The "middle class" has existed for a THOUSAND YEARS since merchants, artisans, and craftsmen could own their own property and thus were neither nobility nor serf.
Put in modern economic terms the "middle class" exists between the dirt poor living paycheck to paycheck (or off government dole) and the folks with capital to invest or enough passive income generators to not have to work at all but still maintain a high standard of living.
The "middle class" today often encompasses both partners working because the lifestyle has inflated, not the cost of the basics or wage stagnation. Look at the size of the homes today versus the 40s. Every family member had a computer in their pocket. There is a TV in every room. Cars are far more advanced than they were. The trips are more elaborate, no more roadside motels with the whole family crammed in to see Disney. But easy credit is a trap, that is true.
Some of you guys are just silly. Get the FUCK out of those big cities by the coasts with that insane real estate and be "middle class" in "middle america" and see how easy it can be. Yeah, there aren't 50 hip restaurants in a mile radius, not every concert rolls through, and yah might have to see a cow at times, but trust me, it's worth it
