Man, batich - you have a VERY odd perspective.
Not much of a devotee of real-world economics, are you? To say that tourism only benefits hotels and restaurants is..well...is infantile.
Exactly WHERE should all these people "go to work", who currently eek out a few bucks hawking tshirts on the beach?
And crime is not a direct result of poverty? Tell that to the folks in South Central LA, Liberty City, etc.
It hasn't occurred to you to ponder a little? Hmmm....tourism way down, crime way up, simultaneously? Reckon there's any sort of connection?
Mark Twain had some outstanding advice. "It's better to remain silent, and have people think you're a fool, than to open your mouth, and remove all doubt."
But maybe it's just me....maybe is better to ignore facts, and just tell everyone to go get a job - without recalling that DR unemployment is pretty high. This means- there aren't tons of jobs out there, even IF your friends, the tshirt hawkers, weren't too lazy to work. Let's stick to your plan- preserve the natural beauty, while crime escalates to the point that no one is safe trying to enjoy it. Yea- that's the ticket. We can all admire the natural beauty from the safety of our armored cars...
