Growth is exactly like Jesus. Some people strongly believe it will return, despite strong evidence to the contrary.
And we're all cargo-culting around it, changing laws, reducing taxes, opening borders to lure it in, like if growth was a wild animal afraid of fences.
Meanwhile, old people live the good life of having revenue without doing anything productive. Good for them, but I'd resent them less if they didn't vote for Trump, May, Le Pen.
