No, why should it?

Because the corporation providing ATC services under contract to the
government(s) thinks it's a good idea?

Mode S implementation is very expensive for ATC.

Perhaps the ATC contractor can get the funds necessary to implement
Mode S equipment installation from the government(s), and then use the
added functionality provided by Mode S to enhance their revenue stream
in the future.

It's as I said: They say that in certain regions iof Europe, Mode C reaches
its limits. As I don't know anything about it, I have to believe it.

Either believe it, or do the research necessary to verify the
allegation.

From http://www.eurocontrol.int/msa/public/faq/faq.html:
Mode S is being deployed because the current SSR systems have reached
the limit of their operational capability. This takes the form of
exceeded maximum number of targets, RF pollution, lost targets, identity
errors and Mode A code shortage. Mode S is therefore a necessary SSR
replacement in airspace subject to high levels of traffic density.


Can European airspace possibly be more congested than that in the US,
say Chicago or Los Angeles?
