Absurdly Driven looks at the world of business with a skeptical eye and a firmly rooted tongue in cheek.

There are so many words pumped out into the world these days. Finding the wise ones can be tricky.

Once a year, however, Warren Buffett offers a few in his annual letter to investors. They're usually sober, sensible and even serene.

He's just published his letter for 2017. All 29 pages of it.

Naturally, it's full of investment material that some will find moving. For example, Buffett wants you to know that he doesn't merely hold stocks for long periods. Sometimes, he actually sells.

Many, though, might be more gripped by his socio-political and psychological commentary.

I'll offer you just a few snippets.

Buffett seems to believe that America has always been great.

"Early Americans, we should emphasize, were neither smarter nor more hard working than those people who toiled century after century before them. But those venturesome pioneers crafted a system that unleashed human potential, and their successors built upon it. This economic creation will deliver increasing wealth to our progeny far into the future," he says.

The famed investor makes clear that his view of immigration isn't quite the same as that of Donald Trump and his intellectual muse Steve Bannon.

"From a standing start 240 years ago -- a span of time less than triple my days on earth -- Americans have combined human ingenuity, a market system, a tide of talented and ambitious immigrants, and the rule of law to deliver abundance beyond any dreams of our forefathers," he said.

Buffett, a supporter of both Hillary Clinton and Barack Obama, hasn't gone out of his way to be quite so overt about immigration before. To hear him be supportive of a "tide of immigration" might trouble those who embrace so-called economic nationalism.

Everything is politicized these days. It's as if personal lives, business approaches and even sporting events are looked at for their political shade.

It's inevitable, therefore, that some will see his comments as a counterpoint to the notion that immigration is something that should be couched in fear.

Currently, we're told that fear fills the world. Don't go to France, don't go to Sweden. For all I know, Fiji's a bit tricky these days. Russia sounds nice, though.

But does excessive fear ever produce positive results?

This is where Buffett moved onto psychological ground.

"First, widespread fear is your friend as an investor, because it serves up bargain purchases," he said. "Second, personal fear is your enemy. It will also be unwarranted. Investors who avoid high and unnecessary costs and simply sit for an extended period with a collection of large, conservatively-financed American businesses will almost certainly do well."

In essence, then, don't be too afraid, America. You're not in such a bad state after all.
