Our recent pandemic exposed a lot of the inefficiencies in our government as well as our broader society.
Our healthcare system is too privatized and fractured to effectively respond to a broad, nation-wide crisis.
Our education system does not teach adequate media literacy skills (much less science literacy) so Americans do not know how to properly sort through sources of information throughout the media landscape. As a result of that, we have different factions of Americans who have their own go-to news sources that simply confirm their own biases. (This is also a result of the balkanization of the media ecosystem caused by the digitalization of the media but that is another conversation).
Our political system is too polarized and fractured to be effective in a nation-wide crisis because crises are politicized for partisan agendas. Also, the two political parties that control the processes and infrastructure are essentially bought off by corporate oligarchs and do not represent the average American. This is why they use marginal, “social issues” to keep Americans divided and ignorant to real issues that actually matter to our common interests.
