That's a bit of a weird point to make, though. That income tax is already going toward paying for government programs. If you divert some of that to pay for early child care, some other programs will be left under- or unfunded.
The reality is that currency-issuing federal governments everywhere run perpetual deficits (and some economists argue they have no revenue constraints at all.) States can't do this.
Unless the subsidy enabled workers to work instead of mind children, and thus pay more income or consumption tax. NOT APPLICABLE IN STATES WITHOUT SUCH TAX.
