Yep, but "Pork" can be a good thing, jobs are important, and the F-35 is any economy booster in lots and lots of communities. That helps everybody, and spreads the love around. The truth is, its an amazing airplane, and a force multiplier!
Our partners are getting their money's worth, its an incredible airframe, with an incredible amount of flexibility and capability for the money!
Coming back on topic, the J-20 is also a great airplane, but it needs a manufacturing base! The Flankers will make up the back-bone of the Chinese Air Force for years to come, but they need to back that up, with a real 5 gen.
So whether or not SAC works on the J-20 or the FC-31, which is also looking more promising! they will be on to some type of 5 gen, trust me on this, I do have my sources!
