This is what I think socioeconomic support will look like in 2040 based on cognitive  quintiles.
The bottom quintile (0-20%, non-voters) will have supported work environments and direct income subsidies; an improved version of what most  wealthy nations do for the 0-5% of adults currently considered cognitively “disabled” .
The second quintile (20-40%, Trump base if white) will have subsidized employment (direct or indirect).
The fifth quintile (80-100%) will live much as they do now.
I don’t know what happens to the 3rd and 4th quintile.

 The US is currently “mainstreaming” the cognitively disabled into relatively unsupported work, a well intentioned and evidence-free project by (my) Team Liberal that is going to end in tears.
 In US male euros (avoid racism/sexism effects) maps to academic achievement which tests learning, social skills, temperament and the like.
