“EPIC also called for the implementation of California’s first state income tax. The tax was to be progressive, with the wealthiest being taxed at 30%. The plan would also have increased inheritance taxes and instituted a 4% tax on stock transfers. EPIC also included government-provided pensions for the old, disabled, and widowed.”
