Others have pointed out that having offices called "czars" is an odd naming choice for a democracy. But czars weren't just authoritarians. They were ultimately authoritarians who left their country far poorer than their more democratic counterparts, lost a world war, and of course paved the way for an even worse system of government. The label "czar" thus doesn't historically connect to a model of strongman effectiveness -- it connects to a model of strongman failure.
(Of course, I recognize that czars in the federal government don't have even a fraction of the truly dictatorial power of their namesakes. But the label was used for a reason, presumably to evoke the positive connotation of strong authority that Gets The Job Done. Yet the specific strong authority that the label evokes proved to be unable to get the job done, at least under anything approaching modern conditions -- under any sensible definition of "job," possibly with the significant but narrow exception of the job of defeating Napoleon -- and unable in a way that culminated with a disaster of historic proportions.)
