Nobody in the USA worries much about the cost of incoming calls either. Truth is, all phone calls are to the benefit of both parties or one will hang up quickly enough. There really is no grand asymmetry. What really matters about who you give your number to is who you want to let interrupt you when mobile.

I would like to learn more about these call-by-call operators and how they bypass the fees. Using VoIP terminators, I still have to pay 20 to 25 cents/minute USD to call most Euro cell phones. They are the only calls left in the developed world that cost an amount of money you would care about.
