As a stupid American whose only knowledge about this topic comes from reading maybe 10% of the comments in this forum on this subject, I thought May was just stuck with an impossible dilemma? From what I understand there is no way to negotiate a good Brexit deal.
Because it was founded on baseless populist sweettalk and not on real economic modelling. Anybody with an iota of a brain cell would have seen Brexit for what it was - a total scam and lie.
Unfortunately, like we've seen in the US, UK and even here in Australia, the average denizen doesn't understand all this jargon about 'tariffs, autarky measures, terms of trade, factor endowments, global financial markets etc.' nor do they care to learn before making rash and uneducated decisions that would negatively affect them in both the short and ling run.
There really is no substitute for education, it's just a never ending cycle of uneducated and misinformed folk voting for the party cutting education funding leading to a generation of even more uneducated and easily misinformed folks repeating the same futile cycle ad infinitum.
