Yea but they don't mean corporations like Amazon ruling over you what they mean is worker or government syndicates. Its basically national syndicalism. Corporatocracy is when actual private companies rule over you and manipulate politicians which we already live under.

Italian Fascism involved a corporatist political system in which the economy was collectively managed by employers, workers and state officials by formal mechanisms at the national level.[36] Its supporters claimed that corporatism could better recognize or "incorporate" every divergent interest into the state organically, unlike majority-rules democracy which they said could marginalize specific interests. This total consideration was the inspiration for their use of the term "totalitarian", described without coercion (which is connotated in the modern meaning) in the 1932 Doctrine of Fascism as thus:

A popular slogan of the Italian Fascists under Mussolini was "Tutto nello Stato, niente al di fuori dello Stato, nulla contro lo Stato" ("everything for the state, nothing outside the state, nothing against the state").

This prospect of Italian fascist corporatism claimed to be the direct heir of Georges Sorel's revolutionary syndicalism, such that each interest was to form as its own entity with separate organizing parameters according to their own standards, but only within the corporative model of Italian fascism each was supposed to be incorporated through the auspices and organizing ability of a statist construct. This was by their reasoning the only possible way to achieve such a function, i.e. when resolved in the capability of an indissoluble state. Much of the corporatist influence upon Italian Fascism was partly due to the Fascists' attempts to gain endorsement by the Roman Catholic Church that itself sponsored corporatism.[38
