You're comparing general statistics to specific situations.  The poster does mention that college is good for certain things.  But, it isn't a blanket cure-all over all vocations/trades.   You also say he's likely to be laid off...which is something you can't say unless you understand what he's doing and what the demand is.

There are good paying vocations just as there are bad ones.  And, there are good paying degree'd jobs just as there are bad ones.  It should be evaluated on a case-by-case basis.
