Armstrong's prediction of shift of economic center of the world from West to Asia is well underway:
..., and certainly a huge portion of the population with any money to spend.
Well the Asians are going to have the most money to spend in aggregate, especially after 2020 as the West collapses. The hightech nerds in the West will still have money to spend, but the 2nd degree relations maybe not. Btw, if you need some convincing on this, check this out and realize that no one in the West will be earning more than about $2 - $3 per hour for any job that can be outsourced online (as the Western Sovereign Debt/Socialism collapse ensues in earnest 2017 - 2032):

Duterte was in China this week to declare Philippines was saying goodbye to its subservient alliance with the USA, he announced telcom deals to upgrade Internet broadband in the Philippines. There are huge 10 story call/BPO centers being built all over Davao for example (and every city in the Philippines).
Asia doesn't have the entitlements, so taxes thus wages can remain low (and China's debt can written down unlike the West's debt which will increase forever until the socialists die) until full employment is attained for billions of Asians (then wages can rise faster for all skill levels). For example look at Singapore's medical system financing:
