CHICAGO — A bipartisan group of state lawmakers is calling for an overhaul of the nation’s childcare system, which they say is failing children, parents and providers. During a panel discussion Monday, lawmakers underscored the persisting challenge with childcare that costs families too much and pays providers too little. “The childcare system is at a crossroads,” the report says, “and decisions made now will shape how well systems meet the needs of families and economies in the years ahead.” Michelle Lujan Grisham last year announced the nation’s first free universal childcare system, funded by state investment earnings from oil and gas revenues. Bannon, of NCSL, said the states are now leading the charge on childcare as Democratic and Republican state lawmakers increasingly explore new legislation to childcare access.
