But no one is willing to pay me to sing. So I talk and write for a living. If I chose to sing for a living I would be justly poor. My poverty would give me no legally enforceable moral claim to the incomes earned by other people. I would have chosen to be poor.
Some people choose to save and invest part of the income they create.
In doing so, they provide the means for entrepreneurs to undertake new ventures, create new products, and provide new employment and purchase opportunities for people. Other people consume most of their incomes. Savers and investors are likely to accumulate assets that will generate more income for them than the spendthrifts will have. Yet spendthrifts have no legally enforceable moral claim on the incomes of savers and investors. The authors of the study may want to grant people who make poor choices an enforceable claim to the incomes of people who make better choices, but there are no moral grounds to do so.
