For a lot of reasons, clearly. But this article explains how democracies are essentially run by civil servants/public servants/bureaucrats-who wish to impose their ideas on a captive citizenry. This is the case in North America, in much of Europe and somewhat in other English-speaking Commonwealth countries. In "The Civil Servants Are the Masters Nowadays", it is very well put:
"How is it, then, that a government is frustrated by the very people it
appoints? Here we come to the huge problem nowadays of our permanent
official and semi-official classes. So weak is Parliament, and so nervous is
government of looking over-political, that these classes fill the gap left
by “here today, gone tomorrow” politicians."
"If you look, for example, at the public appointments rules introduced in the
name of procedural correctness, or of “diversity” (which, by an Orwellian
effect, really means uniformity), you will see that they are run by civil
servants. Naturally, they choose people appealing to the civil servant’s
cast of mind. Everywhere – in the appointment of peers or quangocrats, in
IPSA, the body which decides on MPs’ expenses, or on the Committee for
Standards in Public Life – unelected people lay down the moral law for the
elected. They welcome the opinions of interest groups, and exclude those of
the public and the people the public elect."
