<<Well yes it is hard to understand how this policy would stop Cubans when it won't stop Mexicans.>>
Think about it. It's a lot easier for the Mexicans to get to the U.S. than it is for the Cubans. There's no open ocean to cross.
<<Cuba has less torture and repression now than under Batista?>>
Of course.
<<Then why wasn't there an exodus nearly as large from Batista?>>
Leave, get caught by the U.S. and sent back to Batista and you'll have a bigger problem than what you started with. You'd be returned to a country oversupplied with torture chambers and ruled by a dictator who knows you're pretty unhappy with him and his regime. Not a very happy ending to a voyage that began with such great hopes of streets paved with gold bricks.
OTOH, leave Cuba to escape Castro and you will NEVER NEVER NEVER be sent back. Big difference, even though for some unfathomable reason, you never seem to be able to grasp it.
I'll try to make it real simple for you. Hopefully, you'll agree with me that not too many young men from the Greater Los Angeles area leave their homes and jobs to try to break into the Playboy Mansion and live there. They know the gates will be closed to them and even if they sneak in, they'll be found and kicked out.
Now suppose Hef makes it known that anyone from Venice Beach who makes it onto the grounds of the Playboy Mansion can stay there for life and will never be kicked out. You're an imaginative guy. Try to imagine how many young men from Venice Beach had left everything behind and tried to break into the mansion before Hef made his generous offer. Try to imagine how many would do so after Hef's announcement became known. Think there'd be any noticeable before/after difference? Think the number of guys from Venice Beach trying to get into the Mansion would become any higher than the number of guys from Long Beach or Compton or Van Nuys or Santa Monica or El Segundo trying to get in? I dunno, plane, you tell me. Inquiring minds need to know.
<<Got some examples of Cubans going on desperate 90 mile swims to get away from Batista?>>
No, but then you don't have any examples of Cubans going on desperate 90 mile swims to get away from Castro, so we're even.
<<All of the real evidence is one way.>>
The problem is, you don't have any "real evidence," only MSM bullshit stories of people swimming 90 miles. You don't know how to interpret "real evidence" anyway, because you make heroic efforts never to try to put it into context, even when that context is never further away from you than the nightly TV news. "Real evidence" would probably show the flow of refugees from Mexico is dwarfing the flow from Cuba and is probably followed closely by the flow from El Salvador and Honduras as well, but since Mexico, El Salvador and Honduras are all capitalist countries, there is no reason to set up a giant lure in the form of free admission to all new arrivals and furthermore, there is no way that their flight can constitute "real evidence" of the failure of capitalism.
It seems that it is only the flight from Cuba that can constitute "real evidence" of the failure of communism. The flight of millions more from capitalist countries proves actually nothing at all. That is just plane logic. And it is hilarious.
However, since I see that you are a fellow who loves the truth and is very interested in "real evidence," try to imagine a scientific experiment. Try to imagine a six-month period in which the U.S., instead of granting free admission to all Cubans, warns them that all new Cuban immigrants will be rounded up and sent back to Cuba without exception and that in the same six-month period, all Mexicans who make it into the U.S.A. will be welcomed with open arms. IMHO, not only would Mexico suffer major depopulation, but the experiment would prove conclusively whether or not the Cubans are better off than the Mexicans.
<<On the other hand you have actually been to Cuba , where I only imagine the scene to be like this . . . >>
I think, when all the "real evidence" you have is as pathetically shitty and inconclusive as what you've shown us, you're better off sticking to lame anti-communist jokes dating back to the beginning of the Cold War and forgetting about evidence and "real evidence" completely.
