Lying to the public to maintain power, keeps their hands on the government purse.
Loss of trust in institutions.
Loss of sense of prestige in the traditional tracks, they make up for it by becoming authoritarian to maintain sense of utility.
This has been apparent in the US. Our govt tells us small lies for the greater good - early in the pandemic masks weren’t needed - better to tell them they didn’t work so there were enough for healthcare workers.
Works great until the situation changes and you need people to wear masks. Not only do people question why things have changed, they start to ask what else you’re lying about for “the greater good”.
