It starts off as if it's just a commentary on personal finance, then gets deeper, and explains the almost inevitability of financial strength leading to greater strength, and financial fragility being a slippery slope where a single slip may make a subsequent slide more difficult to avoid. (My metaphor.)
Read it, and start saving, if you can.
I know people don't always read links, so I'll chuck in a few quotes to tempt you.
This number is probably the truest measure of a person’s real wealth: What is the largest unexpected financial shock you could sustain without the cost of that to you suddenly becoming ten times the original cost or more? That number isn’t something easy to calculate; it depends on whether you have a family that can help you out, on your income, on whether that shock involves losing your job (and thus your health insurance, if you live in the US), on whether you have access to any other sources of security (including public assistance).
and
If you want to understand economic class in the Western World today, here’s a simple rule of thumb: There are people for whom a shock that’s reasonably likely to happen within a year — a car breakdown, a lost job, and so on — would be catastrophic, and there are people for whom catastrophic events happen much more rarely. Those are your two social classes.
and
Each financial shock will knock some set of people down a social class, destroy part of their wealth, and redistribute the rest among everyone else. Successive shocks will hit different groups of people, but ultimately everyone will be hit by a few, so the only people who won’t get knocked down are the people who have enough “shock wealth” to survive them.
This is the plain and simple way that income inequality can be created in the absence of any external forces on an economy. No new gold rush has to open up and make a few people rich; no explicit banditry has to happen. Just one financial shock after another.
I like "no explicit banditry has to happen." I think lots of people on the left feel there's a conspiracy against the poor. Forces do work against the poor, no conspiracy needed.
