If the model is broken, should you try to fix it, or should you scrap it and get a new one?
In questions of technology, increasingly the answer is: scrap it. Computer repair shops are dying out: if your laptop doesn't work, just buy a new one. What applies to consumer technology, however, does not necessarily apply to politics.
The political model of Western-style democracy, which grew up alongside and then within a capitalist economic model, is now broken. Exhibit Number One is Donald Trump, but there's lots of other evidence too.
