Some great discussion here.....
In my county, minimum wage is $13/hr. Using

You can see that working just two, 8 hour shift per week, you're able to take home $806/month or $9,672/yr, after taxes and FICA.
Since I'm using a conservative 3% WR, this could potentially replace the need for $320k in invest assets. At current low spending, covers over 50% of my current spending annual spending (55% to be exact!).
A minimum wage job should be pretty easy to find, in an absolutely horrible SOR scenario. If you plug that into any FIRE modeling scenario, the impact is HUGE.
With even a little bit of skills, social connection, luck, etc someone could probably find something a few bucks an hour over min wage rather easily.
In parts of the country where min wage is much lower than $13/hr, the worst case would be picking up a third shift per week.....this kind of resilience is not as easy for someone who has a higher spending level (in absolute terms).
