Last week in Pittsburgh, US President Joe Biden announced a radical plan. Out with the Reagan revolution, in with a $2.3 trillion infrastructure plan designed to create jobs, reduce inequality and discrimination and restore America's status as the world's undisputed superpower, with incentives to innovate and go green. Will his gamble pay off? The same lawmakers who by a razor-thin margin just approved his $1.9 trillion stimulus plan need to sign off on a decade's worth of spending on everything from rebuilding crumbling roads and bridges to affordable housing and renewable energy.
