Population growth and 10% economic growth in fast-developing countries will result in billions more people consuming at the rate of rich-world baby-boomers within a few decades. We’ll have to change our eating habits in the long-run, but until then, how on earth are we going to produce enough food to feed a billion middle class Indians and Chinese who have suddenly developed a taste for hamburger? Meanwhile, a complex concoction of trade regimes, population growth, urbanisation and increasing temperatures mean that food security is an ever growing threat in Africa; but in this case not because the new middle classes are demanding hamburger, but because hunger is still real (more on all of this at Citizen Renaissance here.) So what can we do about it? We can further develop smart methods of farming to increase yields perhaps. And yet if you’re a left-winger, you’ll think GMOs or other farming technologies are Satan’s spawn. That doesn’t make sense. Surely if you’re a left-winger, you want to feed people in developing countries.
If the worst predictions come true, we’ll experience a 5-6ºC temperature increase by the end of the century, putting vast swaths of the world under water and destroying ecosystems and possibly the nature pyramid to god knows what effect. But climate-change scepticism has become a standard bearing right-wing issue: if you’re right-wing, you’ll claim it’s all a load of tosh. That doesn’t make sense. Surely if you’re right-wing you should be just as worried as a left-winger if there’s even a slight possibility that even the most rosy scenario regarding climate change may come true.
Immigration rates in Europe aren’t really out of control as the populist press tend to claim. Three other trends are however. Declining birth rates, people reaching retirement age and Europe’s pathetic economic competitiveness. Right-wingers claim to be pro-business, pro-growth and pro-wealth. And yet right-wingers tend to be, if not always hostile, at least very wary of immigration. Again, that doesn’t make sense. Who is going to buy and build things? Where is the next generation of innovators going to come from if half our population is retired?
I’m fully aware that all three issues – and many others like them – are spuriously ideological in some way i.e. a right-winger will make a political argument for why they are anti-immigrant or a climate-change sceptic; while a left-winger can just as easily frame their hostility towards GMOs in genuinely left-wing terms.
The point I’m trying to make is that most issues are far too important and complex to fit neat political demarcations. And yet politicians and the media who support them are all too ready to politicise them to score an easy win. They’re taking advantage of the age-old human instinct whereby people are comforted by thinking that everything can be defined by us or them / right or wrong; so if the opposition has taken a stand on an issue, the response is to take the opposite view, rather than debating or perhaps even – shock, horror – agreeing with it.
It’s not all bad though. At European level, the strongly consensus-based political model makes complete polarisation difficult. Meanwhile, year after year, voters throughout Europe are increasingly struggling to tell the difference between parties (which I happen to think is a good thing) while age-old political affiliations based purely on family or geography are dying out. But given that the left-right divide can still characterise epoch-defining issues like food security, immigration and climate change, we still have some way to go.
