Legal restrictions on emigration and immigration exist in every country. Do you think everyone in the USA is allowed to get a passport?
All US and all your fellow Canadian citizens have a right to get a passport, unless they have some pending criminal charges, have crazy criminal restrictions ie: on a terrorist watch list, etc.
All Canadian and US citizens have mobility rights, they have the right to leave and return to the country, unless of course they have serious criminal issues like above.
It is the Cuban people who have invested in these educated professionals, not the USA, so the USA should not profit from said investment. If you want to talk about taking the wealth of more deserving people, you should also look at how brain drain works.
Your theory about educational investment is also flawed, since athletes can't leave the country either, without consent. You might think differently if you had high ability and work ethic in Cuba & were subsidizing everyone else via your hard work while the mediocre, dumb, and lazy leached off of you. If you feel bad & want to give them your money, you're free to do so in a liberal democracy.
So what you're saying is that Cuban professionals, and anyone else seemed of high value to the state, are slaves to Cuba? You should look at how slavery and mobility rights work. How basic basic human rights work, as guaranteed in the UNDHR, US Bill of Rights, Canadian Charter of Rights & Freedoms. You and most other communists want to trade so-called "wage slavery" with "high ability" slavery.
