Trickle down does not work.
It will not work for people of the north east or even the country as a whole.
In no other sector does it work, like I said earlier, in charities the money goes to management and corporate bull****. Overall, these massive corporate entities hide their profits into secretive offshore accounts and keep it there, paying no or minimal corporation tax!
You really think that every company involved in anything to do with the future of LHR expansion will care about communities. It is all about bottom line profit for airlines and airport operators. Everything else comes next very low down the list such as paying fair share of tax (not avoiding it like recently shown by GAL at LGW who haven't paid any tax since acquiring the airport in 2009!), environment and noise.
More money, siphoned off to tax havens at the expense to society in the UK as a whole.
