I'm afraid the ride is going to be much rougher for us than simply a 'lost decade'.
In reality, Japan has not recovered from the downturn of circa 1990...so they have "lost" two decades. We will be lucky to lose only two decades.
Japan is failing due to an aging population with no constant source of immigrants.
The Japanese failed to prepare for an aging population but preventing immigration is no sin. They have limited resources and limited space. Yes, it has an impact. See above. But limiting immigration is no bigger a factor than the Japanese propensity to small families. And the change in racial demographics in the U. S. has a lot to do with the fact the formerly dominate white anglo-saxons are reproducing at a fraction the rate the Middle Eastern and Hispanic immigrant population is.
Immigration is not going to solve our problem. It is exportation of our brainpower, technology, and our completely stupid effort to be the world policeman that is hurting us.
We need to seal our borders from illegals and the drugs they are trafficking. We need to punish Americans who use drugs and states that promote its use (like California and the other states with "medicinal" mariuana)...what a joke. Marinol with do exactly the same thing medicinally. Let the government produce it and give it away. The reasons given for not using it is worse than lame, they are outright lies. The one and only reason people want weed instead of the substitute pill is for the high... pain, they could give a hoot about it...
When my previous appraisal partner died of cancer she took marinol and it helped her keep food down and increased her appitite as will as reduced the pain. But there was no "high".
Legal immigration could be encouraged and serve this country but our "legal" immigration policy is a joke and an impediment to immigration reforms.
Let the Iranians "protect" Afghanistan.... Replace our troops man for man with Iranians....and watch them suffer. Replace our troops in Iraq with Chinese troops. You don't see the Chinese wasting their resources trying to herd cats...and we are stupid enough to do it. We were in Bosnia and where were the Europeans? They won't even protect their own backyard. Why bother? The stupid Americans will shed their blood for these ingrates.
