Well that depends on whether you're defining middle class as an income or a lifestyle. If the latter, I would certainly not consider any shared living arrangements as "middle class" in the US. Even if your income band puts you in the top 1%. Now, it's quite possible that they're choosing a lesser lifestyle now in order to save and transition to another lifestyle elsewhere. That's what my brother did -- two years in SV saving as much as possible, then moved back to Seattle and bought a house.

This is why any of these definitions get really murky, fast.

> at what "middle class" actually is in the US.

I think it is deeper than that, the country just has a confused relationship with the entire concept of class by both rejecting and embracing it.

Its "class" we are talking about here and it does exist in the US compare Bill Gates vs Steve Jobs and Woz.

Are those three not in the same "class"?

While Gates was richer than Jobs, once you're in the $100B vs. $10B, you're mostly in the keeping score category. Woz is apparently worth about $100M which is still in the you can buy pretty much anything you want category. So I would say yes.

On the other hand, someone who is worth, say, $10M or $20M is obviously still quite wealthy. But not necessarily in the doesn't need to think twice about hopping on a private plane or owning a private island category.

Not initially anyway its not all about money

So what is it about? You're acting like we should all know what you mean. Typically when someone talks about class they referring to income, wealth, and sometimes debt.
