Basic income mean huge changes:
For example, salary may still be partially driven by necessary education / experience, but physical, tiresome or stressfull works would requireask for way higher salaries (because you get up at 4AM to collect garbage when you have no other choice, or when you think it really is worth it, and those jobs would still be necessary)
The same way, some companies will have huge problems filling the ranks (let's say: food industry, waiter, marts cashiers (or the people filling the mart at night), ...
But education industry (and universities) would have to change their methods, because nowadays peoples are willing to commit 100,000's of $ to get a well paying job, this incentive would be gone, the better paying one being the physical labor, with low education requirement.
I also wonder if people would go with their lives the same way they do now. I, for one, would get one of those hard, high-paying job straight out of high school for a few year, enough to buy a house and save a bit, then go to university (or self-studying with internet classes, choosing some classes in common with friends) and study whatever I found get my interest.
TL;DR: I'm all for Basic Income, mainly because I don't see any long-terme viable alterative, and also because the changes it would bring to society would be really interesting to study.
