@"Before getting too deep into it I will note that they don't deny the figure that the bus claimed that we send to the EU, they simply bemoan that the funds will not be heading to the NHS in the aftermath - so we can safely take it as read that the charming remoaners don't deny that we sent (and still send, while negotiations are ongoing) upwards of Eighteen Billion pounds to the EU every year."
Ok, so ignoring the fact that this isn't the net amount; and that the UK negotiated a massive rebate to cancel the effect of farm subsidies (ie everyone else has the pay the EU's farmers, but the UK having less of an agricultural industry, pays less in). After you leave the EU you will have to A) pay for customs and border agents to do more work or B) remain in the customs union/common market and pay the EU for the privilege (but have no say in rules of said market).
The same is true of nearly all other funding. Money spent by the EU on least developed regions (which you can see here in red: https://upload.wikimedia.org/wikipedia/commons/2/20/European_regional_policy_2014.svg) like the coast of wales and cornwall; and the transition regions (Northern Ireland, northern England and the north of Scotland, among others) will dry up, so it does give the British govt the option to not pay for regional development.
I guess i don't trust that the British govt will do anything positive with this power, given that historically they are the reason those regions are less developed than the EU average.
You probably will get the benefit of not paying the for the administration of the EU, which is ~6% of the total budget.
Or will suffer from govt cutbacks in all areas that Westminster decides not to fund - which is the actual lie here. Either you get 350 million for the NHS, which comes out of cutting back on things the EU currently funds, or Westminster decides NOT to redirect this funding to the NHS, and hey presto; the govt doesn't like giving the NHS money, because if they keep up their chronic under-funding, they can increase the anger and resentment the public harbour for the NHS, and eventually privatize it (ie sell to their mates at mates-rates and see a huge profit).
No matter what, the intention was to fuck the public.
