I don't think that "people need jobs to have any kind of leverage in society" is actually true, though. Retired people without jobs are (in-)famously known to be politically powerful, both regarding elections and regarding local political questions apart from elections (like city planning commission decisions).
The jobs they worked turned into capital which is where their leverage comes from. So it's still applies.
Their leverage is a result of having the time to be involved in politics, which is itself a result of working for decades to build up to the point that they could retire. They're an end result of the system, not an exception to it.
