A puncture in my tyre: Keynes, Smith and GDP in the UK

I've just fixed my bike, after the second suspicious puncture in the back wheel tyre. Suspicious as it occurs at night: romance, chance, or more likely cheap financing, as per recently surveyed by the Guardian?

Adam Smith wrote about the needle factory in 1776, perhaps similar sharp objects hit my wheels tonight. Just a coincidence or is a new Industrial revolution, the 3rd to date, forthcoming!?

I got my wheels punctured twice in less than three years:  you need to be street-smart and bike-street-smart in London!

If active bike thieves keep punching tyres at a sustained pace, how many bikes will they reap by so doing? How much money to bike shops, and any unintended actions there!? Enough to revive stagnating domestic demand (for tyres) in the UK? Would John Keynes agree on similar reasoning, and Mr Cameron?
