Lee essentially answers this question by arguing that the "Right" has already won - a situation which isn't consistent with what a stand-up comedian does (as he puts it, the clown's act relies on not being able to get what he wants).
"Ultimately, the left will lose. Big business will pollute the planet, capitalist culture will kill off the arts and humanities, schools will all be privatised, libraries will all close, social mobility will cease, the gulf between rich and poor will grow and everything beautiful will die. The left may note little human rights victories – gay marriage and the odd bit of better pay – but the machine is rolling inexorably forwards to crush it."
Do you agree? Do you think that modern comedy is indeed prevailingly left-leaning as Lee does? If so, do you think this explains it?
