Gross domestic product based on PPP valudation of country GDP matches the “county” MegaLounges so far, predicts Japan next. Have I solved the puzzle?

My thinking as it happened.

If I’m right, the next MegaLounges will be /r/MegaLoungeJapan, /r/MegaLoungeIndia, /r/MegaLoungeUnitedStates, and finally /r/MegaLoungeChina before we need a new theme.

Edit: Further evidence: I note that all of these lounges already seem to exist (with the exception of United States, which could be going by a different name e.g. US, USA, United States of America etc.).
