People in the prime earning years of their work careers are leaving it all behind. Some have no plan at all except to be done with what they used to do and look forward to perhaps consulting options or other opportunities. Others resigned with the intentions of helping with their grandkids as the burden of at home schooling and work and having something of a marriage was taking its toll on their kids. The numbers for the Midwest are clear, with quit rates climbing to all-time highs, as shown here by FRED.

For some the virus has made life too stressful. The uncertainty of whether your kids have a reliable place to be during work hours is a significant concern under any circumstance. The last minute need to take leave from paid employment to look after a quarantined kid creates an entry on the positive side of the on-going debate whether the family would be better off with one worker dedicated to family affairs.
Many people settle into the extended family model where grandparents or aunts and uncles show up for a childcare shift throughout the week. This also alleviates the stress of transport to and from daycare in twenty below weather sliding over ice covered roads. The anxiety of a worker when faced with being late to pick up their infant is palpable.
People are making quality of life choices.

Once people start sharing such ideas with others, a little self-reflection can set off a chain reaction.
Labor, like any commodity, is compensated by a mix of pecuniary and social rewards. Where individuals, couples, or extended families find the balance of enough cash and enough time to keep the family support systems in play so that everyone is safe and fed and healthy. And then there’s the altruistic side of people who feel the sheer reward of adding to the public goods market whether through education or their many other talents.
