And I will assert that the reason the costs for such Ada systems don't
come down is, in fact, the Mandate.

Consider.  Most of the current customers for such systems are doing
Defense work, where Ada is mandated.  They are, in effect, consumers
in a captive market.  This artificially pushes the demand curve to a
position where demand is artificially high at each market price and
the elasticity of demand is quite low.  Hence, the supplier in such a
market will exercise what is, after all, only good business sense, and
will price their product artificially high in that market.
Arbitrarily lowering their price in that kind of captive market
situation leads to lower profits (since they make less on each of the
'mandated' purchases).  This is why you will likely never see anything
like a 'Turbo Ada' while the Mandate is in force, unless the
government funds the thing itself (trying to correct market
distortions caused by government intervention through the use of more
intervention).

In this kind of market, at least some people who would otherwise
choose Ada (if the software were available at the real free market
price rather than the artificially high price created by captive
demand from the Mandate) find themselves priced out of that decision.
While the increase if 'free choice' users might more than make up for
the loss in profits from 'mandated' users if the price were to be
lowered, in the short run this will be a losing strategy; so it isn't
going to happen, more than likely.  Thus, the Mandate itself helps
create the situation where only people who are forced to use Ada will
do so (because of the price), which creates the necessity for the
Mandate (in somebody's eyes).

Solution?  Ditch the Mandate.  Let Ada compete on the basis of its
merits in the same kind of marketplace that other languages do.  It
may win and it may lose, but I think one thing you'd see is the prices
of Ada systems coming down to compete with other languages and
language systems that provide similar functionality.  There would
perhaps be an initial drop in systems being built in Ada as people
previously subject to the Mandate selected other languages, but I
suspect that that might be more than made up by other systems being
built in Ada as the prices for Ada language systems coming down under
market forces and people decided to use it.
