Dominicans have always been the overwhelmimg majority of construction workers. It was in the late 90's to early 00's that Haitian worker share in construction begsn to be considerable, today making most of the construction workers. In the mean time, something that never existed before is that it has become quite common on many islands in the Caribbean to have Dominican construction workers. Hmm, I wonder where were they before?
The sindicate for Dominican construction workers has been denouncing for many years the abandoment of Dominican construction workers in favor of Haitian ones. Aside from maintaining wage levels near stagnant, the equivalent if a wage cut as time goes on, many Haitian workers are (or were) illegsl immigrants and that mesnt greater savings for Dominican companies as they don't have to pay things such as paid vacations, social security, on the job health insurance, etc. Usually, the prestaciones are equivalent and in many cases surpasses the wages and salaries a company has to pay. In essence, the influx of Haitian construction workers is a way to increase the amount of money going into the pockets of the company, owners and top managers. That's one of the reason why construction of torres had a profitability level that went as high as 60% (think that percentage of the money that costs you to purchase an apartment in a torre went as pure profits). Torres are known as gold mines among certain circles. For example, a torre built anywhere in the USA doesn't produces not even half the profits that one does in Santo Domingo and certainly not as quickly either.
