I mean stanger things have happened in political history, every amendment to the US constitution that expanded the right to vote was passed by a country of leaders elected before those expanded rights went into effect, meaning the wider voting pool would inherently risk negatively impacting them even insofar as having to spend the time and energy campaigning to the newly enfranchised.

Taking for granted that the rich and powerful can never be made to accept changes wich negatively impact their wealth and power is a dangerous game of giving in to the most advantageous form of cynicism to the rich and powerful, the kind where you stop expecting anything of them and stop pushing for accountability when they fail those expectations.
