The economy is a world of offer and demand, between production and consumption.
Banks invested in area's where demand was increasing strongly till it reached a peak, resulting in short term gains as you say but long term losses.
Property values fall, which means buyers with less financial power will not easily get to buy a house but will more easily buy a car (car prices drop aswell), fuel, food and rent apartments for less money, which leaves more money for leisure and travel.
A downturn in the financials and real estate sector really don't harm the economy as much as the economists and media pretend.
In Ryanairs press release that goes with MOL's appearance in the media this morning they mention profits going lower still despite 'profits from aircraft disposals'. If RYR are contemplating shrinking their fleet then that it very big news indeed for the industry.
MOL is not contemplating shrinking his fleet.
"One hears what he wants to hear".
Anyway a recession in Europe and USA is very welcome for my company ;-)
