It's a shame but it's true. It's the same reason why Russia and
  much of China's systems are antiquated as well. Bigness. The USA
  has an additional issue though: The way we're politically set
  up. Our 50 states have a lot of powers on their own. The whole
  USA thing is "Big Momma" watching over its little ones. But the
  Federal part of the USA is kinda limited in what it's allowed to
  do. Not impossible but there's a constant negotiating between
  "States rights" and "Federal rights" and the way our system is
  setup is fundamentally SLOW. The slowness keeps the government
  stable... that's the theory anyway. == The only time we're a
  "country of ACTION" is when we're bombing somebody else.
  Internally? Slow as molasses. == The thing is, the money's tied
  up in politics. EVERYBODY wants control of the same pot of money
  and they fight over it. The "Richness" is tied up in fictional
  real estate prices. Tied up in fictional stock values. Tied up
  in fictional bonds. Tied up in fictional "value" of tangible
  goods. Tied up in fictional "value" of services. Free flowing
  money? Eh. It's not. Slowness. == Yup. That describes the USA
  pretty well. I like surprising fellow Americans by letting them
  know that if you make more than $34,000 (USD) a year, you're in
  the top 1% of the planet. They always get mad because they're
  busy looking at the super-rich, not realizing that THEY'RE only
  a few stones away from the top of a VERY tall pyramid.
