After Rik Veldman and Charles Bow invented humanoid pseudo-animals the Elysian senate passed a law which established a tax on the ownership of HPA slaves. One of the arguments in favor of this tax was the idea that this tax would discourage people from owning slaves and to encourage manumission. However, in practise the profits made by slave-owners exceeded the tax obligation by such margins that no HPA had been set free because of this tax.
Though the slave tax had been most vocally supported by those who opposed the enslavement of HPAs, the Republic of Satelliteland maintained this tax after independence. Of course, many slave-owners did insist on the abolition of this tax but the government of the newly independent country was in great need of funds. In contrast in Elysia this tax was abolished immediately after HPA slavery was abolished.
Ever since independence the government of Satelliteland has increased the rate of the slave tax. Opposition is virtually absent in the Satellitelandic politics, save for a few radical nationalists.
Economists are divided over the virtue of this slave tax – ignoring the immorality of slavery. One school of thought states that it is an efficient tax on wealth, as the wealthy own more slaves and will hence pay more. However, another school believes it would be better to abolish this tax altogether.
