Edge cases do not negate the whole point. For example, I'm pretty sure you can find a billionaire who's very cash-poor, i.e., wealth is locked up in the value of a private company. Does not change the fact that anyone with $1 billion+ of net worth is ultra-rich. Whatever the edge case may be, anyone with $1 million+ annual income and $10 million+ in assets is undeniably upper-class, including your hypothetical farmer. Note that I never claimed their assets should be taken...just stating an objective definition for upper class.
