Until reading this post I had assumed that the age shown in your profile (3) was an unfortunate typo - now I'm not so sure.
In a capitalist economy, such as the UK's is, a business that makes no money for it's owners / shareholders is often closed down, and the site redeveloped - and as an unfortunate consequence people lose their jobs.
Many airports in the UK are losing money, some with threads on PPRuNe, are verging on dead ducks, even though local supporters often can't see it. UK airports are not akin to the NHS (a sacred cow that anyone who suggests radical change is lambasted) they are businesses that stand or fall on their financial (not their social) viability.
