Tobias's original plan had been to teach impoverished adults and single moms computer literacy so they could get jobs. But when Tobias asked businesses if they would hire YSM's grads, they laughed. They told him bluntly that a lack of white-collar social skills—never mind computer literacy—barred most poor people from employment in Toronto's silver and gold office towers.
