Challenges for America in the coming decades

Let's face it, folks: America has some serious long term challenges ahead. Of course, every country has problems, but I believe America enjoys some particularly difficult ones, and Americans aren't exactly rising to the challenge as of yet. Let me list some as I see it:

• Public deficit spending. As of this writing, America's national debt is over $9 trillion. At an approximate national population of 300 million, that comes out to roughly $30K owed by every American, a large portion of which is owed to foreign governments. Furthermore, running any prolonged, substantial government budget surpluses is unlikely in our political climate, as that would be interpreted as over-taxation. It's just a matter of time before the U.S government is unable to meet an interest payment due on the growing debt, and then the party's over.
• Private deficit spending. We're selling off our assets to by foreign manufactured goods, as as well as oil. This is also related to the negative national savings rate. We must import capital for economic activity.
• Declining dollar. This is pretty much a direct result of the previous two. This wouldn't be so bad if it weren't for our dependence on foreign oil and foreign manufacturing.
• Rise of China. China is widely considered to be the next rising economic superpower, and we're dependent on it for our manufacturing and our financing. We're gradually ceding our economic sovereignty to China (and other foreign creditor nations), and as their affluence grows, so will their consumer markets and geo-political influence, eclipsing our own.
• Looming demographic crisis. America is getting older, and the rather large and significant baby boomer demographic has already begun to retire. This will hit the public with a big double-whammy: the large social security and medicare obligations, coupled with the loss of their working tax income. That's on the public side - on the private side, companies are seeing their experienced workers heading out the door, and are desperately trying to import replacements, both high skilled via H1B, and low skilled by lobbying the government to continue their tacit approval of illegal immigration. The heath care system will also undergo a significant strain as the baby boomers age and require medical care.
  

These are some pretty heavy problems, and it's difficult to see a painless solution...
