Analyses abound about [what's wrong with American democracy](https://rationalwiki.org/wiki/Essay:Problems_with_the_curren...). The nail in the coffin though, will be the first part of your sentence. The American Constitution is notoriously hard to amend, which means that it is just too easy to maintain as it is by those who benefit from the status quo. We can already see this by how the will of the majority is routinely ignored through unequal representation. My opinion is that this is not sustainable and will have to be resolved through unlawful means, exactly because of the unflexibility of the law.
