A successful and well functioning democracy requires constant monitoring, involvement and pressure from citizens to hold it accountable, otherwise it gets captured by monopolies and malicious actors with money, who will steer politics in their favor instead of the citizens' favor.

The problem with that is that most citizens today are too burdened by the cost of living and sorting their own lives to have time and energy for political activism. The only ones who do are retired boomers and they only care that their pensions and house prices are going up.
