(In my opinion, the Dutch system is one of the best implemented in practice, precisely because of its proportionality.)
the most massive political injustices, poor housing, health care, education, elderly care, affordable transportation, queer human rights, all of them despite high GDP, just to name a few quantifiable properties of a state... the worst digressions happen in FPTP systems currently.
also the article throws both hands in the air as if no mechanisms exist to further improve democracies. it doesn't mention popular vote, or some mechanisms for balance of freedom of speech vs freedom to slander and distort and lie ("hate speech", the word polemics has 'polemos', war, as root), or press codex, or application thereof on all media, including "social" media, ad engines made of letters to the editor largely left alone and unmoderated... nor does it mention panachage and cumulating of votes on lists, the right to adjust the party list proposals in the voting booth.
the article does mention the brazen influence of financial power as a problem though.
but really, proportional representation is part of the solution.
Then there the focus on the left vs. the right, which is no longer as relevant as it used to be during the cold war. If you choose a single faction (such as the left, conservatives, or environmentalists), that specific faction is almost always smaller than everyone else combined. When there are multiple major issues instead of a single overarching question, political divisions become more nuanced than simple X vs. not-X.
