Too Small to Survive

In higher education it seems that it is not "too big to fail", but "too small to survive".  Another small, private college outside of Portland to close at end of year.  The list is getting bigger and bigger. Again, will we see any small public colleges close in next year?  What is limiting closures and mergers in the public college sector?  Is there a bubble to burst out there?
