Since this thread has talked about balanced and unbalanced treatments, I guess I'll have to admit to being unbalanced. Oh, wait, we were talking politics?...
The concept of balance applies in politics like it does in other parts of life, and even in the Yin/Yang symbol. (And would you believe that the smilies on this forum don't include that symbol?)
The whole point of the government laid out by the USA Founding Fathers was that EVERYTHING was seen as compromise in a world which was guaranteed to be impermanent in its characteristics, with what we call "checks and balances" to prevent a runaway government. We don't have a king or a royal family with power. England's monarchy is symbolic because they are governed through Parliament. We don't have a permanent dictator like North Korea. Our leader potentially gets changed out every four years. Our members of Congress change out potentially every two years for the House and six years for the Senate.
For a long time, Congress did what was called "logrolling" - originally a big balancing act by a lumberjack rolling a log in a lake and trying to stay afloat / above water on a constantly moving, slippery surface that bobbed up and down, tilted, and rolled. The government found many compromises and kept the country going, trying to find a balance point that offered at least some care of poor people but allowed people who could do it to not stay poor. Welfare and Medicare and Social Security are some examples of offering help to poor people.
I'm not sure I can put a date on it, but a long time ago we started slipping away from the compromises that kept us going reasonably well. Here is the thing about compromises - NOBODY likes everything about them but EVERYBODY likes something about them. "Every dog gets a bone." Well, a lot of people decided that wasn't enough and wanted more. But a funny thing called reality stepped in. Sometimes there IS no more. Witness Greece from several years ago. Witness the City of Detroit within the last few years. I believe Chicago isn't far behind. When too many people demand too much and claim it as rightfully theirs, they ignore the fact that they didn't earn it.
The "entitlement" mind-set is largely to blame for the problems here. Poor people have lost track of the fact that taking stuff from someone else is theft or robbery. People (particularly prominent Democrats) bemoan the loss of Democracy, forgetting that we never had it. There was a phrase that was popular a few years ago speaking of the "tyranny of democracy." A "true" democracy can reinstate slavery against a minority and make it law. This is what the Founding Fathers desperately wanted to avoid. That is why we have TWO chambers in our legislature and why their representation is not handled identically. One is by population, the other by geo-political boundaries. Thus, in the Senate, Wyoming and Vermont (the two least populous states) have equal footing with California and Texas (the two MOST populous states.) The House is based on population alone, with a rough average of one Representative for every 700,000 persons (give or take a few percent due to rounding).
This bizarre dichotomy means that the tyranny of the majority has to get through the Senate where all states are equal. You can't easily ram-rod a bad piece of legislation through Congress except in rare moments when the "election pendulum" has swung too far, leading to serious imbalance in the Senate. Recent case in point: The Affordable Care Act a.k.a. Obamacare.
Since the 2nd Amendment to the constitution defines the right to keep and bear arms, it will take a constitutional amendment to revoke that right. Which means that amendment would have to be ratified by 2/3 of the states (rounded up). That's 34 states. So back to Tera's question on whether we would be able to do something about gun rights - surely we can. But we have to get 2/3 of the House AND 2/3 of the Senate to agree and then we would have to get the president to sign it. We CAN make changes; we have done so in the past; but I do not see this one coming any time soon.
