100% this. This reminds me of what my SO says: if you have to work, you are not in the upper class. I don't think I agree with this statement fully (I personally think that top decile by income is already upper class), but I feel like I'm becoming more open to re-evaluating my opinion...
Most upper class work. They work different jobs, but they are generally not sitting around retired. They might or might not get a paycheck, but they are working. (if you own a restaurant you will probably pay yourself minimum wage when you do work - dishwashers start at double that - talk to your accountant but this is often the best legal way to handle your hours that are trackable) Steve Job's was famous for taking a salary of $1/year - he clearly was working and upper class.
Most middle class don't have to work either - they are just not willing to accept the lifestyle that forces. Even poor people could find enough savings by 30 to not work if they really want to live that lifestyle. (I don't blame anyone for not wanting to live like that)
> they are just not willing to accept the lifestyle that forces
Jeez the pedantry around here.
Let me spell it out: Upper class people don't have to work to maintain their existing lifestyle. Steve Jobs could have continued wearing black turtlenecks and paying fines for parking his Mercedes in handicapped spots for the rest of his life, without doing a lick of work. That he didn't is a credit to his work ethic and passion for the work.
Out of curiosity, how much money do you think is needed to survive ~55 years ("savings by 30" + life expectancy around 85ish = 55yrs) without working? Also, please spell out biggest assumptions you're making.
