But the populism doesn't address the issues either and and their incoherent points will make things worse. Just look at the US for example.

Indeed, this happens when you sacrifice public dialog for short-term gains calling everyone who does not agree with your points "far-right", "nazi", "russian asset". There will be literal fascists and people will support them just because they promise(probably bait-and-switch, but does not matter) to address public problems instead of gaslighting that problems are non-existent.
