It's hard to believe what went wrong in US Navy procurement. Labor cost along can't explain the vast cost differences (054A is around $200 mil, the smaller LCS is above $400). Maybe they were victims of formalism to serve politicians, maybe because the oppositions were too weak. In any case the past success were built on a pragmatic approach. Given the fact US is almost always involved in at least one war, there are plenty of opportunities to get whatever process fixed.
Have some confidence in the US. One thing you have to understand is the media in the US is always critical of the government. So overall there is sense of negativity existed if you only read the media.
Cronyism and pork barrel politics are an entrenched part of the US system. The problem is that its net effect has been off balance in recent decades, it has been hijacked to serve big money and corporate interests too much, instead of or at the expense of the public or the common good.
