The distinguishing factor for being working class/owner class is whether or not you make the majority of your income from your labour, or from your capital.
Incredibly well-paid working class, but working class all the same.
A regular family home with 4 bedrooms near the office is $3M or more. If you have to save aggressively for 10 or 20 years to own a home close to work, then you are at best working class.
Not if you have a visa to worry about. Doesn’t matter how much money you have then. You need another job in 30 days or you and your entire family are at risk.
