As I said - sanity lies in the tension between the three components. All three have proven themselves to be not in the best interest of the country. The best place lies in the balance of powers.
But, I take umbrage with the idea that the success of unions caused there to be two classes: privileged union members and oppressed non union members. That is silly. At no point did the unions (even at their greedy bloated worst) say others should not unionize.
Every leg of this will ask for more than it should have - that is the point of a balance of power. But, at this point you really need to ask yourself why we weren't able to compete with people making $3 a day and would we have been better off lifting them up instead of pulling ourselves down.
The republican/democratic paradigm is a falsehood Clinton was the best republican president we ever had. Look at what the parties say they stand for - then look at what they do. They do what the economic gurus tell them to do and we all lose. This is not consipiracy theory nonsense, it is about how the ethos of our economic system evolved and why it got so toxic. The answer isn't to swing 180 degrees but by golly we had better start a pull back here soon.
