From the latest Gary Shilling effort (as sent around by John Mauldin):
Beyond the current recession, the worst since the 1930s, lies years of slow growth, as we’ve discussed in past Insights. The next economic recovery, which will probably start around mid-2010, will likely be so subdued that it may not feel like the recession has ended. And economic growth in the bulk of the next decade will probably be slow — so slow that it will force the federal government to take continuing actions to prevent high and chronically rising unemployment.
Lots more here, most of which I agree with.
