As soon as your accumulated capital becomes large enough that you earn your income only as a result of your capital, then you are no longer working class, and that’s when your interests diverge from the average worker and average homebuyer or renter.

Interestingly, almost everyone in government is a member of the capitalist class, largely because people that sell their labour can't afford the time, let alone the money, to run for office.

In case you wondered why the interests of labour are grossly underrepresented in government, despite that vast, vast majority of both citizens and voters being of the working class, this is why.
