The form of surplus extraction determines political and state forms.

Evidence

The specific economic form in which unpaid surplus labour is pumped out of the direct producers determines the relation of domination and servitude, as it emerges directly out of production itself and in its turn reacts upon production. Upon this basis, however, is founded the entire structure of the economic community, which grows up out of the conditions of production itself, and consequently its specific political form. It is always the direct relation between the masters of the conditions of production and the direct producers which reveals the innermost secret, the hidden foundation of the entire social edifice, and therefore also of the political form of the relation between sovereignty and dependence, in short, of the particular form of the State. — Hall, Stuart, Essential Essays, Volume 1, 491
