Great article here on the practical side of being poor: it is difficult to save. Period. And that difficulty results in a rapid snowballing effect when life intervenes. In this case, a towed truck becomes a lost job becomes homelessness. A good reminder to financial advisers of the dangers of sounding too preachy when exhorting families to save and invest. For some families, this is an enormous hurdle. Worth the brainpower of top bankers to see if they can tackle this one. What great PR for Wall Street if they could actually address Main Street problems.
