One simply answer - Money. It all boils down to Money. Haitians come to the Dominican Republic in search of better living conditions. Buscones do their part and help smuggle them in. The companies who run the Batey's are not complaining much either as they get 'free' labor. And the Dominican Government does not have the money nor apparently the organization to prevent both illegal crossing and illegal smuggling, as it would require an entire mentality change toward why accepting bribes is not a good thing and why. Things will not change greatly until CESFRONT really starts clamping down. And thats not going to happen until they can resolve within themselves why accepting bribes (and other benefits) is not worth it anymore.
