They <i>might</i>, but <i>will</i> they? My experience is that most people really don't want to run businesses. They want to come to work, do the job, get paid and go home. Most also go for a comfortable lifestyle rather than absolutely maximizing their income (too much work!). In that case, the college student who likes computers will probably choose to work in that field for $9/hour rather than for $10/hour at WalMart.
