There’s some pretty sound thinking, here. The very American perspective, though, obscures the obvious equivocation on ‘work’. Not all meaningful work has to be work in the labour market for pay, and work undertaken without pay (notably child care and home-making) has every bit as much right to be regarded as character-building, status-affirming, and demonstrative of personal value and significance, as that undertaken for money.
The author does not raise a question that strikes me as crucial: even if we assume that each human is valuable and respectable in proportion to how much their work contributes to their community (an assumption open to debate, at the very least), why assume that the only way to evaluation that contribution is by looking at what some affluent person is willing to pay them for the service of making that employer even more affluent?
Economists believe in full employment. Americans think that work builds character. But what if jobs aren’t working anymore?
