Probably to clear space. In many places, vo-tech/technical programs are being phased out. In others, these programs become the type of place where you send kids that aren't old enough to send to jail. Unfortunately, nowadays if you want to go into the skilled trades (and you manage to not let your guidance counselors talk you out of it), you either go to a technical college or you learn by playing around with stuff on your own time. This is unfortunate, because college certainly isn't a silver bullet for everyone. There are lots of smart, skilled tradespeople that can't write a research paper or do calculus but can build a house, rebuild an automatic transmission, etc.
