Was reading a year or more ago that the pot back in the 60-80s when I was growing up is not like the stuff grown today. When I was in school and through college it was recognized that pot was a drug but, it was not considered a drug with the addictive properties of the other drugs of the day. Today through bio/agricultural engineering pot is much more potent than it was and it can be an addictive drug. It is far more potent than it was 30+ years ago. Hash/hashish was very potent back in the day and modern pot can have almost the same potency of hash of yesteryear...
Have read a few cases where graduates whom weren't able to find work turned their degrees in agriculture to building and setting up indoor grow sites that were very high yield productions.
When I worked in Telecom in the 80s - 03 I had a Russian office-mate for a while and we would talk about the cultural differences between Russian and the US and the economies and industries and the like. One reason the hacker community was so large in Russia was that many computer graduates could not get good paying jobs after graduating. The hacker cabals would pay them a very good wage. (There's an entirely different system in place in Russia where you are paid above and below the table, the government taxes the above the table wages and the other is not. Very different ethics from what many are accustomed to in the USA. But this is an entirely different can of worms.)
