HARRISBURG, Pa. (AP) — Gov. Josh Shapiro will unveil his first budget as he aims to remake the state’s public school funding system and to put Pennsylvania on competitive footing with other states to attract major companies. The Democrat will deliver it to lawmakers Tuesday. One big Shapiro campaign promise is to cut Pennsylvania’s sky-high corporate income tax rate by more than half within two years. Shapiro also is vowing to make a “down payment” on the billions of dollars that public school advocates say are necessary to fix disparities between poor and wealthy districts. But Shapiro is saddled with a slow-growing Pennsylvania economy, grim demographic trends and what he calls a “workforce crisis.”
