“There are those who look at things the way they are, and ask why,” Robert F. Kennedy famously said. “I dream of things that never were and ask, ‘why not?'”

RFK was an idealist — someone who views the world as a blank slate full of possibilities.

So am I.

Realists — people who strive to make improvements within the constraints of the current situation — are important. No society can live with its head in the clouds. But we also need people who look to the stars. Where are they now?

For as long as I can remember, American politics and media have been dominated by self-identified realists to the exclusion of idealists. In many cases, the “realists” are just bullies pushing agendas with no real grounding in reality (c.f., Bush’s neo-cons). Still, some of these Very Reasonable People, as Paul Krugman calls them, have achieved incremental victories that have made life somewhat better in some respects (c.f., Obamacare).

But no civilization can achieve greatness without idealists. If you’re looking for one big reason the United States seems to be on the wrong track, try the marginalization of idealism that coincided with the collapse of the peace movement and the American Left at the end of the Vietnam War in the early 1970s. The death of every strain of American Leftism from liberalism to revolutionary communism has left us with a nation that doesn’t know how to dream big.

If we’d been like we are now when Sputnik launched, it’s a fair bet we never would have gone to the moon. We couldn’t have justified the massive budget. Or it would have died in Congress. The money would have been spent, but on stuff no one needs — invading foreign countries, tax cuts for the rich and big corporations — with nothing to show for it.

America has become too small to fail.

In an excerpt from his upcoming book that appeared recently in The Atlantic, Michael Wolraich recently discussed the tendency of Robert La Follette, the Wisconsin senator and leading light of the Progressive movement of the late 19^th and early 20^th centuries, to hold out for radical progress over incremental, less satisfying gains. La Follette’s big-picture approach — so idealistic — was, in its way, more realistic than what passes for realism today:

“He might have passed more legislation by compromising [with his enemies], but he refused to dilute his proposals. There was that stubbornness again but also strategy. La Follette took a long view of political change. In contrast to Roosevelt’s pragmatic approach, he believed that temporary defeat was preferable to compromised legislation, which would sate public demand for reform without making genuine progress. ‘In legislation no bread is often better than half a loaf,’ he argued. ‘Half a loaf, as a rule, dulls the appetite, and destroys the keenness of interest in attaining the full loaf.’ Legislative defeat, on the other hand, served a useful political purpose. He would use the defeat of a popular bill to bludgeon his opponents in the next election, and he would keep assailing them with it until they yielded or lost their seats.”

Or, as the revolutionary “situationists” who took over Paris in May 1968 cried: “Be realistic: Demand the impossible!”

When I read this, I thought: Yes! Here’s a perfect articulation of the politics we’re missing.

With USA Today recently joining the chorus of media describing Barack Obama, who championed realism in the form of diminished expectations, as a failed president and a “lame duck before his time,” and Hillary Clinton once again marketing herself a yet another drab uber-realist for 2016, a reminder of La Follette’s ambitious approach to politics is especially timely.

Consider, for example, Obamacare.

La Follette would see the Affordable Care Act as a classic case of the “half a loaf” that “dulls the appetite” for true reform — in this case, socialized medicine or at least European-style “single payer.” In 2007, before Obama and his ACA came along, 54% of Americans favored single-payer. Now, thanks to a system that’s better than nothing but not nearly good enough, it’s down to 37%. Hillary Clinton is endorsing Obamacare, and has officially come out against single-payer.

Democrats defended Obamacare to liberals and progressives as an imperfect, insurance company-protecting interim measure. Obamabots encouraged libs to support the conservative Democratic president because the ACA would move America closer to the single-payer ideal.

Now we see how wrong the “realists” were. As La Follette would have predicted, the appetite for the “full loaf” of single payer has diminished, partly sated by the “half loaf” of Obamacare. Regardless who wins in 2016, single-payer will be off the agenda for another four to eight years. Obamacare killed single-payer.

Imagine, on the other hand, where we’d be if Obama had gone the idealist La Follette route, proposing a single-payer healthcare reform bill that had suffered defeat at the hands of Congressional Republicans.

Six years after the beginning of the 2008 economic crisis, several more million of Americans would be uninsured. Hospital emergency rooms, bursting at the seams as it is, would be in a greater state of crisis — which would add to support for reform. You can easily imagine Obama and the Democrats beating up “Republicans who don’t care about sick and dying Americans” on the campaign trail. Sooner or later — I’d bet sooner — they’d have to cave in and vote for this big new social program, just as they did with the New Deal and Great Society, or face oblivion.

Of course, Obama’s appetite for single payer was never ferocious. He promised a single-payer “option” during the 2008 campaign — yet never tried — but the point remains, the American people allowed themselves to be “realistic.” Which left them with far less than they might have gotten had they held out for full-fledged single-payer.

As we head into the 2016 campaign, remember what “realism” really is: the siren song of mediocrity, written by the elite to make you settle for less than you deserve.
