I don't get this mentality at all - if you don't have savings to cover 3 weeks, what are you going to do if you become unemployed? I "only" have about 4 months worth of salary saved and I feel like I need to watch my expenses, cause that is not enough.
Well in my almost 20 year IT career, I've only ever been unemployed for 3 months. For the last 10 years, I've had two jobs.
What does anyone do in the US who finds themselves unemployed? They scramble to find a job..any job to make ends meet and when that doesn't happen, they live out of their car. And when they lose their car, they live in a homeless shelter.
