Mr. Biden would also invest $80 billion in personnel and technology enhancements for the I.R.S., in hopes of netting $700 billion in additional revenues from high earners, wealthy individuals and corporations that evade taxes.
Republicans and conservative activists have criticized all those measures. Administration officials told reporters that the president would be open to financing the spending and tax credits in his plan through alternative means, essentially challenging Republicans to name their own offsets, as Mr. Biden did with his physical infrastructure proposal.
Still, many of the details in his new proposal poll well with voters across the political spectrum. Much of the package could win the support of the full Democratic caucus in Congress, which would need to band together to pass all or part of the plan through the fast-track process known as budget reconciliation, which bypasses a Senate filibuster.
Expanded access to government-subsidized preschool and community college may have broad appeal.
Workers with only high school degrees are often stuck in low-wage jobs, and two-thirds of mothers with young children are employed, and thus need reliable child care. The high cost of quality day care and pre-K puts these services out of reach for many families, who may rely on informal networks of relatives and neighbors who are untrained in early education.
Expanding access to pre-K has been particularly popular over the past decade in states and cities, including some with Republican governors. A large body of research shows that achievement gaps between poor and middle-class children emerge in the earliest years of childhood and are present on the first day of kindergarten. Administration officials contend that free, quality early childhood education can both help cash-strapped parents and build students’ skills in ways that will help them become more productive workers.
Still, there are major disagreements about how generous any expansion of pre-K should be. President Barack Obama’s administration generally favored a centrist approach in which new seats were geared toward lower-income families.
