Well I can say this my grandparents lived under Batista and things were better than they were with Castro,when they left . Contrary to what Animal said not all rich people were the ones that left Cuba after Castro came into power,and most every middle class person wanted Batista out . Many middle class families like my grandparents were and lower income families also left Cuba. You have to understand Castro lived upon the farmers was fed by them and given shelter by them and that's how his support grew. Not only that but many, many, many, people with University degrees and "rich" people wanted Castro to succeed because they simply hated Batista. Most of them wanted a democratic government which they felt Castro would bring to the country. Instead they got a Communist Far Left dictatorship. That went from bad to worse.
Some on my grandparent's extended family and friends fought against Batista with booby traps and gathering intel for Castro. I t was a very frightening time and still my mother and aunt remember vividly the sounds of planes overhead and explosions,they heard when they were very young children .
There's a whole bunch of things that were better in 1950's Cuba ,before Castro than after the Cuba missile crisis and Castro's purges after he took power in 1959. But still most people not only the poor wanted Batista out,they wanted democracy in Cuba. As you've seen in later years many more people left Cuba during the 1960's after the big exile early in the decade.
