Health economists are criticizing the Biden administration for withholding crucial details about an ambitious proposal to invest $400 billion in reforming the home caregiving industry, a move they say erodes public confidence that the massive funding package will be spent wisely.

The Biden administration included the proposal in the $2 trillion American Jobs Plan, an infrastructure package that aims to repair thousands of bridges and roads, expand high-speed broadband, and fund development of new clean energy technology to combat climate change. The $400 billion initiative is meant to make home-care services for the elderly and disabled more accessible as well as boost wages and provide health benefits for “underpaid and undervalued” home-care providers.
