Not what it could or perhaps should be...
I'm all but certain there is a lot of charity going on, but the term "charity" should be used loosely.
Many of the machismo examples (cars, beer, loud music, parties) so far are surely abundant, but there are quite a few of the old school that have contributed mightly.
Without going into names (b/c I can't remember them) there is a lot of community development that's been done and continues to be done; medical, education, food, etc.
Beyond that, the Pedro Martinez foundation has been a conduit for charities towards the most recent flood tragedies.
Just fan donations alone at Fenway have been $11,000. David Ortiz, Manny Ramirez and Pedro have asked their teamates to also donate. No idea on the amount but I'm sure it's pretty good.
I know Raul Mondesi donated a fire truck to his hometown of San Cristobal, but seeing cement doesn't burn, I'm not sure what real value that holds, but I'm sure it made a nice picture.
Beyond that, I think the baseball (players) in the DR has contributed in the greatest way by giving the nation a strong sense of pride and accomplishment. Sure they haven't cured any ills, but they have put the DR on the map for most of the Western world.
Of course, it's what brought me to the DR, so perhaps my sentiment is stronger than most.
