I know a place.  

 I seen that graphic the other day. UK here, none millionaire. Staying put😕😂.  

 Singapore… Interesting. 🤔 

 A decent place so long as you don't like cannabis.  They'll kill you for holding an ounce of it. 

 Also I just realized this photo should be read in reverse. If you want to become a millionaire, you go and live in China or UK. 

They are factories producing millionaires. 

 Respectfully, I don't think the lived experiences of the middle class in those places reflects "upward mobility" as you imply.

The map is not the territory 😉 

 it would be interesting to see Argentina information.
But it might be very soon to have any data. 

 This is bogus, there’s NO WAY people are coming to Canada anymore 

 Canada is still probably preferable to China. 

 UK is a surprise to me. 

 More so the number than the fact that they're in the red 

 Is it nominated in usd or local currency?

That must be a wake up call for some big countries….
