The Future Belongs to The Unhappy

It seems the future belongs to the unhappy:

"The findings of happiness research are mostly unsurprising. If you’re a nation-state, your population will be happiest if you’re a wealthy, liberal-democratic, capitalist, welfare-state with a low rate of unemployment. Who knew! If you’re a mere flesh-and-blood human mammal, you’ll be happier if you get more sleep, get plenty of exercise, work at a job that fits your personality, don’t spend much time stuck in traffic, have a stable marriage with a compatible partner, spend plenty of time with friends, pull down a decent income and … don’t have children. Yeah, that’s right: kids are a drag." Will Wilkinson

Why then does the future belong to the unhappy? Because they're the ones having babies of course...
