"Same with Trident, the Lefties want to scrap it, well scrap it if you want, but don't moan when thousands lose their jobs and whole areas of the country are blighted with unemployment. You can't have it both ways."
The point is that they are employed in making something that is totally useless. If we spent the same amount of money (and actually MORE jobs than Trident because they are very highly paid), we could solve most of our domestic problems.
Or...we could employ them to make chocolate teapots - just as useful as Trident.
