Of course the part about night programs and scholarships is a lie. Only very few of the best qualify or can afford those programs. Try to spend 12h driving a car or doing deliveries then say 4h in school. I dare anyone who espouses this to actually try to do it. (Note: due to commutes you're forced to sleep a few hours less than typical and so are additionally disadvantaged.)

If this were reduced to say 12h total it is (barely) workable but now were talking about a part time job which can sustain the person for a few years. That mythical beast exists only in a few specialties. (All of them high tech and very well paid. Not something you would expect a typical taxi driver to be able to pull off without education and training.)
