To be enslaved is to be forced to labour without pay. What distinguishes slavery from mere voluntary work is the element of coercion. If you work unpaid for a third world educational charity, you are volunteering. If you are taxed to pay for the education of the third world under threat of jail for non-payment, you are enslaved.

So, ironically, Gordon’s plan is to commemorate the abolition of slavery by raising taxes, effectively forcing the salaried to slave unpaid on his plantation for a little longer. Slavemasters of old convinced themselves they were furthering the greater good by bringing Christianity to their slaves. Gordon taxes us for “the greater good” of the third world. Plus ça change, plus c’est pareil.
