Those alternatives are indeed all taxpayer funded, but not all act as a subsidy to employers. There was a paper contrasting EITC and guaranteed minimum income, and one of the notable differences is that EITC is a slight subsidy to employers, while GMI is actually the opposite. GMI creates (some) disincentive to work, requiring employers to pay more to attract the same employees.
