dirigistes (الجمع dirigistess) (no plural form needed; already is a plural)

"But we have not, at least by 1997, observed any postrevolutionary reduction in the zeal of the dirigistes, who seem, genuinely, to consider themselves both epistemologically and morally superior to their fellow citizens."; James M. Buchanan in Politics by Principle, Not Interest: Toward Nondiscriminatory Democracy, pp. 208, 1998; vol. 11 of The Collected Works of James M. Buchanan.
