You're comparing apples and oranges there, in fact you say it straight out: "you learn different things during a CS degree". It's not a web development course, which is why there's such a big gap in time. I could believe finding a well-produced collection of courses equivalent in material to a CS course for say $1000, but not $50. Not by a country mile.
