America is doing well right now, and there are benefits and drawbacks to both unicameral and bicameral systems.

The House of Lords needs to become more meritocratic, and the 17th Amendment should abolished to make Senators more dependent on State legislators and divorced from destructive populism.

American government is among the most inefficient and useless in the developed world.

Governments are designed differently. Some level of inefficiency is acceptable to Americans if it results in political stability. The United States is one of the oldest extant political organizations, so it seems to have worked well.

The Senate is the more austere chamber. It's filled with more qualified representatives and they remain in office for much longer. It makes sense that these men would have a far bigger role on matters of foreign policy and federal appointments.

I would say right now American inefficiency of government is at a critical level. It is gridlock. With legislation at such a standstill, it's a clear impact on stability of the government. Even countries with relatively unstable governments with a dozen political parties involved are more efficient than the American system. You have people that aren't that far ideologically apart but are gravitating towards the extremes of their parties so it appears extreme. The Democrats have a right leaning moderate in the Whitehouse, but the party itself is orienting itself much farther towards the left. The Republicans have leadership who are essentially also right leaning moderates yet the party is orienting itself towards fierce antagonism towards the Democrats and its goals are much farther to the right. It's an awful system.

There's much better systems. Canada is a good example of an incredibly efficient government. The only problems people have with our system is viewing the controlling party as having too much power and some low level corruption within a legislative body with no de facto power.

Haven't you seen Fox? Obama is a communist-socialist-crypto-islamifascist. That's how most tools on the Right act. Not the bright ones, but the average rabble in the trailer parks and suburbs.

Yes that's part of the problem. American media resembles tabloids more than legitimate news. You have pundits that are neither experts nor possess a basic, fundamental knowledge of politics whom enjoy rambling and making biased/false assertions in the spirit of "entertainment". Which the general American population, in their naïve beliefs believes to be legitimate political analysis.
