Here is the ad which infuriated Trump so much, he does not want to continue trade talks with Canada.

I hope this gets a gazillion views.

Trump ends trade talks with Canada after ‘anti-tariffs’ ad featuring Reagan

Parallel situation in the UK. Margaret Thatcher former PM and friend of Reagan is seen by the right wing, free market, anti-EU, Brexit crowd as a secular saint. But it was she pushed the EU into creating the single market, ie free trade zone, in the EU against opposition from protectionist states. So now the EU has no tariff or other barriers but the 'free trade' UK does and it's costing us dear.

Worst hit of course is the food sector. Fresh fruit and veg from southern Europe and fish from cold northern waters were both traded freely to the benefit of all. Now they are held up at customs for hours or even days which adds to costs and means they are much less fresh when they finally get to the shops. So we pay more for worse.
@pthane that is a good point. A sad point, but a good point.
