The recovery bill would also aim to “build back better” by focusing on some long-term problems for America that have also been Biden priorities for many years.
He is keen on a giant, climate-friendly infrastructure boom to correct decades of under-investment: the average American bridge is 43 years old.
Government research and development (r&d) has dropped from over 1.5% of GDP in 1960 to 0.7% today, just as China is mounting a serious challenge to American science.
Mr. Biden would reverse that, too, with more r&d in tech and renewable energy.
He would scrap Mr. Trump’s harshrestrictions on immigration, which are a threat to American competitiveness. And he wants to raise middle-class living standards and social mobility.
That means more spending on education, health care and housing and a $15 minimum wage, helping 17m workers who earn less than that today.
