Another good question from twitter:
Don’t raid your retirement even to put food on the table when you’re out of work. Agree or disagree?
For the most part, I agree. That is if by "raid your retirement", you mean take an early withdrawal from a tax-deferred account like a 401(k) or 403(b). With a few exceptions like taking cash for a downpayment if you're a first-time homebuyer, early withdrawals from these plans do far more long-term damage than short-term good. For one, you lose the principal (the amount you take out) and thus any interest you'd make on that money over the years. That could be a substantial loss if you're in your 20s or 30s and still have two decades to pile on that interest.
Second, by taking an early withdrawal, you'll pay a heavy penalty on top of being immediately assessed taxes on money that you otherwise wouldn't pay until after you've retired, when your tax rate would be lower anyway. If you're in dire straits now, think how you'll feel when the government's tax bill comes at the end of the year.
That said, if taking money from your retirement is your only option and you're really, seriously on the verge of starving, it's probably better to not starve. But for most people who are still capable of finding some kind of way to put food on the table (have you filed unemployment or sought part-time work??), this is an absolute, positive last-resort of all last-resorts.
