Well, if they can't pay for it, the funders will be unable to raise the money and even if planning permission is given, the project will not happen. To a greater extent at LGW than at LHR there will be market testing and that is a virtue of the system, accepting that it is a regulated market.
I think yours is not the only view Skippy. While many would accept the prime need is for hub capacity, they would also say that there is a need to consider what to do if that cannot be delivered at an acceptable social and economic price. Then, what you are doing is (a) increasing the size,comfort and quality of the waiting room as you have put it innumerable times, (b) increasing the capacity of the London and SE system for dealing with point to point traffic which IF the forecasts are correct will be desperately needed by the time the capacity is on line
I read you to be saying that LGW should not proceed under any circumstances. I'm surprised.
