The problem with Spain is that there literally are no jobs, and those courses are a charade.
There are plenty of jobs to be created, also in Spain.
Second, jobs don't exist until they are created; saying that they could be created doesn't help unemployed people. Someone has to take the (sometimes very high) risk.
The limits on how much can be fished is a good point (but I assume the limits is in place to avoid over-fishing, which would result in no fish at all).
Stating that jobs don't exist until they are created may not help unemployed people, but I still believe it to be true.
People would only build the homeless man a house or sell the starving mother a fish if they had something to give in return, at least in the naive purely free market economic sense, but that is how macroeconomic observations on supply and demand operate - irrespective of choices made outside of economic rationality.
