Karen Paciorek teaches early childhood education at Eastern Michigan University. She joined us today to talk about why the high cost of early childhood education doesn't translate to a reasonable rate of pay for educators.
This segment was produced in collaboration with Michigan Radio's State of Opportunity project. Support for State of Opportunity comes from the W.K. Kellogg Foundation, a partner with communities where children come first.
