Well you are also correct and it is important to remain positive.
There is an ongoing shift of wealth in the UK. There is little doubt the fraction of the population that has large disposable incomes is growing and will probably continue to grow as the economic climate deteriorates.
Of course it is up to GA to attract as large a number of pilots from that fraction as it can.
The danger is that aviation is a minority "sport". Ten wealthy individuals will not keep an airfield solvent, whereas ten wealthy individuals and twenty less wealthy individuals will.
We may see the intermediate sized airfields as vulnerable as well as the larger maintenance organisations that are totally reliant on GA. We may also see the schools that rely solely on ab initio training as vulnerable.
On a wider issue it will be interesting to see what the future holds for the price of fuel. There are those that say the days of "cheap" fuel are gone forever. At the moment the tensions in the ME between Israel and the Arab world and in particular Iran are unlikely to go away in a hurry. Other producers are not minded to increase production and / or are capable of doing so.
The world order is changing. No longer are the Americans the dominant super power. Their influence is diminishing, even if they are kicking and screaming about it. Unfortunately we have even less influence now that we ever have.
I am not sure I would want to be starting out today but then again you certainly would not be short of a challenge or two!
