It is fine to have these machines and even fly them well. They are like all sophisticated machines expensive and difficult to maintain.
What bothers me is that we are fighting with 30 and 40 year old machines. We are a generation behind our most likely adversaries. Now out stuff is good, but at some point we need to replace the Apache.
I fear we have focused so much on stealth, we forget that a few super expensive planes and helicopters do not have the same effect as a large number of good robust ones.
