The thing is, @K13, that going out with no deal is by no means an end to anything. It's the start of a new negotiation process where the UK has to negotiate a trade deal with... the EU (and every single other country and trade bloc you want to trade with). All trade will happen on WTO terms until trade deals have been put in place (the EU's recent deal with Japan took about ~6 years to get through). WTO terms are about as bad as it gets so you'll surely want new deals in place (which will take years). The problem with having to negotiate new deals is that is that you're not part of a large trade bloc any longer and will have to negotiate from a position of desperation and with very little leverage compared to a few years ago. This is also why a lot of people are fairly confident in saying that the UK have fecked themselves over. There's no way the UK will get better trade deals from a position of weakness. Add to that that the UK can't agree with themselves what they want anyway.
So yeah, the work doesn't end at all with no deal, it'll be much more difficult getting favourable terms and the people in charge are either mostly interested in power and their own wealth, utterly incompetent or both.
I have heard this argument many times but again looking at it from the other side whilst being on your side many believe it will make trade negotiation stronger because it is a 1 on 1 deal rather than all the EU.
To suggest it will be more difficult if we don't have a deal does not necessarily stack up. I appreciate it is not the same but when buying I have found that being a free agent gets me a better deal.
I am sure there are people interested in power/wealth - you get them in all walks of life but there are in my opinion many dedicated public servants as MPS as well.
