Now sit down, concentrate and let me explain this to you.
Someone might say as a generalism that "everyone's got tattoos these days". Of course everyone hasn't really got tattoos these days and the person making this statement doesn't really mean that absolutely
EVERYONE has a tattoo. They mean that these days so many have tattoos that it seems like tattoos are universal. It's a comparison to something that has gained a lot in popularity. Of course, conversely, statements like this can also be used the other way around to mean something has declined greatly in popularity,
COMPARED to years/decades ago. This is what was being alluded to with the decline in British manufacturing.
Now this is the last I will say on the subject because your total lack of any comprehension and evident pedantic slowness is frankly quite boring. As are you.
Jeez! Don't it lose something when you have to explain in minute detail the subtleties of comprehension, humour, the meaning of life, etc, etc, etc to liberals!
