Since 1959, Cubans fed up or upset with government restrictions or general living conditions have been fleeing island by any means available – gaining exit papers and not returning, making homemade rafts and sailing away on ocean
At times, Cuban government has instituted penalties of up to 10 years in jail as deterrent for people thinking of ‘Sailing to Miami’
At one point in 1994, up to 500 Cubans a day were landing on Miami Beach after sailing from Cuba on home made catamarans, cars with floating devices tied to them, inner tubes tied together, etc.
U.S. treating illegally entering Cubans like everyone else who enters in that manner instead of instant special treatment upon landing which is current norm
Cuba becoming more lenient on freedom of speech and travel outside of country – which may lead to Cubans realizing that life outside of Cuba no what expected or that much better, and returning home
U.S. and Cuba reopening trade between each other – leading to medicine and other goods being more accessible to average Cuban
Cuba transitioning into a more democratic system of government – allowing people to have more of a say in what happens in their government, and disallow several nations, including U.S. reason for not trading with Cuba
