I worked all my young life, in Iowa, on a farm. One of the most dangerous jobs in America according to the actuarials. No lasting damage to me, though not all my cohort actually survived unscathed into adulthood. Heck, half my fathers' generation had nicknames like 'lefty' and 'stub'.
Should working children on farms in Iowa be banned? Had it happened when I was young, half the family farms would have gone under.
Its not some academic third-world issue. You ate that food we produced. And at the time, it wasn't going to be produced any other way.
