It should be noted, how-ever, that only about 1 out of every 10 STEM workers has a high school diploma or less. Those with gradu-ate degrees in a STEM job earned more than $40 per hour, nearly $4.50 more per hour on average than those with non-STEM jobs.

So, already, simply making some simple assumptions and using internationally recognized wage figures for Cuba, we arrive at an average hourly wage of about 12 to 15 cents per hour.
