So shouldn't tge wages in this game world reflect tge economy of that time?
This is exactly what they do and have always done. And the global economy, to which they base their salary requests, is in no relation to profit/loss of single, or a group of, airlines.
(This has been modelled basically from day 1 like this.)
(= EXACTLY like it works in real life. Just a single example; my employer made losses last year, but still we are getting some payraises this year too .. They do have a savings campaign going on, but it's an efficiency campaign and not to cut salaries. And same with everybody else - as it seems that you perhaps quite do not understand how corporations work; the people working there are in no way liable, nor interested, on the company's result (in general level). The only thing they care is how much they earn and what they can get with the earnings. If everything else gets more expensive, hence the bread example of inflation (which I see you really didn't figure out yet?), they need to be paid more. And they want that regardless if the company makes +$100mil or -$100mil per year.. So welcome to the real world
(And also - to add, you cannot compare salaries of two airlines in different countries. $1700 or $3000 to customer service staff is not comparable unless you specify which airlines they are and where. $1700 in Papua New Guinea for example is relatively MUCH MUCH more than $3000 in Norway. The country differences in income levels are also modelled. An airline based in a "poor" country can pay less than one third in staff costs in relation to some airline in a highly developed country - but the demands are also much smaller with less premium passengers, and so forth (again, quite relative to real world).)
