I've learned things today. Things which might be of importance if one were to believe that this is not an illusion. I am not of that persuasion but consider it a puzzle which my mind finds worth playing with. It seems to me that the Biden Admin's idea toward improving their home conditions is exactly the right one to pursue. This won't help stop the migrations until jobs start being born in any nation trying to make such changes (which is unlikely) so the short term answer would be for these migrants to make Costa Rica their goal. They would become a problem for the Americans who took their wealth and moved to Costa Rica. As those migrants began to get kicked out (I'm guessing being Latino would be a strong advantage) the new Costa Rica would begin to swell Northward. Possibly it would quickly become a mecca for growth and innovation and art and jobs? This would be helpful of South Americans to start ASAP because the States Of America are unable to accept such swarming activity and survive. It's one or the other and survival seems the greater of the two.
