It's easy to favour higher prices in dollars when you actually earn in dollars. But not all of us live in the States.
The current exchange rate in my country is $1 to 3,5. So a $60 DCS sim is actually quite expensive with an average income per citizen around $600, when most people earn around $300 or less. And you still have to eat, keep warm in winter and pay the bills, not to mention DCS requires pretty expensive hardware to run. Raising prices will make it impossible for many simulation fans from poorer countries to keep buying ED's products.
It's a simple calculation - 10 people can afford a $60 game. ED gets $600. If out of the 10 people, only 6 can afford an $80 game, ED gets only $480.
It takes a certain amount of money to make software, but once it's done, the cost of selling copies is minimal with digital distribution, so your overall profit depends on how many people buy the game. So please, ED have some consideration.
And the rich guys over here need to stop this kind of discussion, it's not beneficial in any way. If you feel ED deservers more money and you can afford it, buy several copies and maybe give them to your friends for Christmas or whatever - the developer gets paid and you contribute by helping expand the potential customer base.
