Why do you mostly keep making reference to a problem? I just can't see it.
Flying is a blue collar function that many (me included) enjoy doing. It will prove very hard to make a plausable living performing a blue collar function that others would love to do for free (or even pay to do).
Why is this a surprise?
I think it's fabulous that our 'subject' is going to get his chance to enjoy himself. More, given that many others are going to get some benefit from his self indulgence. Air Fares are approx 10 years 'en retard' with actual RPI and thats before we take due note of the oil prices!!
Truth is, in the absence of these giving individuals such as your brother, many would not be able to enjoy a summer break in the med. We should all be thanking him.
