Why is Broadband more expensive?
Regulatory hurdles, low population density, and we are one of the largest countries by area on Earth.
Why do we pay more for healthcare?
Because America subscribes to a warped version of capitalism that places things in the private domain when most other governments wisely decided to manage these things. This includes, but is not limited to, basic utilities like water, electricity, telecommunications, internet, and even roadways. This policy benefits a tiny fraction of Americans -- perhaps 1 in every 250 Americans, while harming the rest, and it is not changed because our government has essentially been co-opted by wealthy private interests and corporations. As our popular media is controlled by the same, the illusion is presented of choice regarding political affiliation and candidates, when in fact no choice exists.
Why is our productivity so high compared to real wages?
Because we don't take vacation, or sick days, and have no labour party present to defend workers' rights, leading to the majority of states passing variations of Right to Work laws which effectively ban unions and allow employers to fire people for any reason, at any time. As a result, the rights of workers suffer, leading to institutionalized abuse and exploitation of workers. Should labor prices rise, it is easy to simply order Congress to flood the affected market with immigrants and crash the labor price.
Why does our government spy on us and disregard our civil liberties?
All governments do that. Ours just got caught. As far as why they do it, the reasons are too numerous to list here, but effectively it comes down to national security and preventing any widespread political insurrection amongst a highly exploited worker caste.
Why are we below the average in ability according to OECD?
Because we invest very little in public education, and the price of post-secondary education is inflating at double digit percentages every year, effectively eliminating access to higher education for many, if not the majority, of the population.
Why is the gap between the richest and the poorest on par with that of African countries?
This isn't entirely accurate. Japan has the lowest wealth inequity of any country on Earth, and the highest is Bolivia. The United States, while scoring nearly the same as Uguanda, also wasn't that far off from the United Kingdom. Source The problem is not a wealth "gap" per-se but rather that when you plot wealth distribution as a curve, the United States has an uncharacteristically high concentration of wealth amongst the top 1% -- far higher than any other country on Earth.
There are many reasons for this, but essentially it comes down to a lack of inheritance tax and how our economy has been structured; We are much more an investment and service-based economy than most, and both of these, but investment in particular, leads to rapid wealth disparity being created. Deregulation of the stock market, banks, etc., also have contributed significantly to this problem -- we are, as it were, robbing Peter to pay Paul. See also: Too big to fail. While the impact of any one of these legislative initiatives isn't enough to change things, collectively they are excerting a continuous pressure on the economy and over the past thirty years the problem has worsened. However, the retirement of the boomers has acted like a catalyst, rapidly accelerating this trend.
And finally, why the fuck do people keep telling me this is the greatest country on Earth?
Because we live here. Duh. Nobody's national anthem starts with "We're Number Two!"
