Why Republicans' main attack on Biden's infrastructure plan doesn't work

Since Covid-19 erupted last spring, Washington came to the rescue with more than $5 trillion of fiscal stimulus. That unprecedented rescue effort helped prevent the economy from plunging into a depression.

Now, even though inflation is surging and unemployment is shrinking, President Joe Biden is calling for spending another $4.5 trillion on infrastructure, education and childcare. That bold agenda is raising concerns that Democrats are about to overheat an already-booming economy.
