It's top-down, because to engage in any endeavor of size requires some sort of organization 1) to actually direct the organization and 2) to amass the necessary physical capital necessary for the enterprise.

Capitalism solves those two problems through the modern corporation which by selling tradeable claims on the profits (through shares) and the owners (shareholders) through an elected board hiring of directors hiring managers.

Other systems which we have seen through history solve those problems through taxation and either appointment from the political class or professional bureaucracy. That is why it's top down.

(While the latter system may seem appealing, it's feedback and informational characteristics are even worse than that for capitalist managers.)
