Too many major forces are converging worldwide for this to happen. At the same time. I doubt motivation is (macro)economical or about increasing world gdp anymore.
For the scale it reaches it's odd the only political opposition is Brexit (that hasn't materialized yet) and Donald. It's not very often one witnesses such a long continued agreement in democracies..
Democracies typically headbutt all the time in the most sensible subjects at inapropriate times. Why does this particular one brings such consensus on old guard ruling parties?
