Take me as an example. I am 8 years in US, married to US citizen. Green Card holder now and couple years ago our plan was for me to become a US Citizen and us to raise our kids on US soil. Not anymore.
With all the outcoming gov scandals, with government forcing you to vaccine your kids, with you or your children going to jail for drawing a gun, for swat team breaking into your house because you are selling raw milk, for all this growing nonsense and my personal disgust with president that calls death of 4 us officials in Bengazi a "phony scandal", I am genuinely sick and disgusted of this to my deeper core. And here comes important part: so you say to me in response: if you don't like it, move out! And you are damn right!
We made this decision recently and right now my wife is learning my native language while I am shifting more towards doing more remote programming gigs. Surprisingly after I moved here from the country of communism, now it seems safer and more sane back in Europe than here! Europe has its problems of course, but honestly I believe Europe will deteriorate much slower than US. Here everything is on fast forward and yes examples like Manning or Snowden revelations and lack of echo makes it hard to believe anything will change for better in the future.
I believe I am not the only one who draw this conclusion lately. I also think that many smart people coming to this country to live "american dream" are also smart enough to realize the economical situation become so unstable that its better to "wait and see" back home.
