Rubio's father was an idiot

Marco Rubio is on TV as I write this, introducing Mitt Romney at the Republican National Convention.

Rubio is talking a lot about his Cuban parents who, he falsely claimed, fled the revolution there.

His father had polio as a child. He couldn't perform manual labor. So his parents sent him to school. He was the only one in his family who went to school. He was the only one who could read. Then he came to the United States where he had to work two jobs and would come staggering home exhausted each day.

And, therefore, we should hate Castro?

How is this story of his father growing up in abject poverty in capitalist Cuba an attack on Communism? How was he doing anything but making a case for Communism? Is that what Rubio and his ilk want Cuba to go back to---child labor and illiteracy? How is his polio-stricken father working 18 hour days in Florida praise for corporate capitalism?
