Earlier quoted context omitted.
We should but you know personal responsibility and all that jazz. The wealthy only care when the pitchforks come out. The biggest achievement of the wealthy has been to convince the middle class to eat itself.
But personal responsibility is actually an important concept. It is completely unacceptable to not have $400 on reserve for an emergency as a functioning adult. That is a situation that can only be achieved by poor decision making and a lack of personal responsibility. Any strategy that is employed to remedy this has to contend with the fact that the individuals who need to have this situation remedied for themselves…
What makes $400 the ideal number? Probably nothing, except the fact that it makes for the best headline, since "2 out of 5" is a quotable statistic.
Formulating advice should follow a different pattern. The ideal number for emergencies is probably closer to $5,000 since it covers more realistic emergency scenarios.
$500 might cover food, gas, a few taxi rides or train tickets and basic OTC medication like asprin for possibly a week.
$5,000 might cover a lost or stolen laptop, plane tickets, hotel stays, car repairs, emergency rooms and ambulances and out-of-pocket prescriptions, funerals, rent or convert to a month's worth of basic needs (food, gas, short-haul travel).
More is obviously always better, but emergency response is about covering the cost of capacity to react, plus supplies needed to take action, plus duration of endurance. $500 wouldn't keep you off the street for more than a weekend, but $5,000 could last a month or more.
