That is exactly the point. Just because a country builds their own ships doesn't mean that they will have fewer problems.
If you boil it all down, the reality is that almost all, if not all of the major defense contractors are loading up with retired military. These folks know how to work the system (since they were on the other side of the table at one point) and avoid accountability. Since the people they are negotiating with will all be seeking jobs in the future nobody is looking to rock the boat.
Incorrect - the POINT was that Australia unlike this country does not ignore its military and treat them like last week's dirty laundry.
Its unfortunate the Collins' boats experienced the issues they did - and they were clearly imperfect. However unlike this country which prefers to cry on command, wring it hands and only spend money on the military when embarrassed and called out publicly on the subject by the US and others (I know for a fact Britain has done so for years, albeit quietly), the Australians don't stare at their shoes pretending the world is a nice happy place full of unicorns, warm milk and magical faeries.....
Its pretty damning when the defence "strategy" of a wealthy first world nation - a founding member of NATO - relies primarily on the good graces of the tax paying citizens of its neighbor to shoulder the bulk of its defence because it doesn't have the stomach for it.
As a British military study released in the mid 00's noted "Canada - almost uniquely among sovereign nations in the 21st century - has virtually abrogated responsibility for its own national sovereignty" - Translation: we're too cheap to defend ourselves so we'll happily slink to the back of the room, sit in the cheap seats, and let the Americans do the heavy lifting.
Even worse then our government then turns around and has the temerity to tell veterans returning from military operations which the government sent them on, that there is no money for pensions or counselling but "amazingly" that same government can always shell out billions to bail out its buddies at some Quebec-based corporation whenever the latter cries "wolf".
