Yeah why would anyone care more about the millions of people who live in cities than the few thousand who live in fishing towns?
I can't believe you can type these words without realising how much of a wanker it makes you look. I mean, aside from it basically saying "fuck the minority", your "few thousand" comment is wildly understated. Grimsby and Cleethorpes alone (both right next to each other and essentially the same urban area) has over 100k people. I can't be fucked to check the population of every coastal town, but we're easily talking millions across the country.

People moving to where the opportunities are seems like a reasonable idea to me.
Ensuring there are opportunities everywhere seems like a better idea to me.
