Sure. And you should probably do that. But then a lot of other people are of the opinion that they can ignore food and weather and come to Britain. Net migration numbers in recent decades have not gone in favour of your line of thinking?
UK high street is being attacked from multiple sides, from apparent lack of labour satisfied/pressured into low wages, to having their access being cut by the latest LTN measures around the country. Rental market is getting squeezed hard by the latest measures that will only make the situation worse, esp for London (I'm lucky I've escaped that place when I could). Current/incoming gov't is drunk on high taxation and more and more regulation of every facet of your life and business. But I'm still unsure my business/work would fare better in any other european country (forget Brexit, it doesn't have much to do with any of this). The malaise is everywhere.
