I think this is the key point, "53 percent say they found better job opportunities outside of IT occupations". I don't think tech employers are willing to provide the pay, benefits,and working conditions necessary to attract the workers they want.

Tech employers are also unwilling to invest in employees. It's hard to find a decent entry level position right out of college. We can't expect college graduates to be %100 ready on day one, they need on the job experience.

Too many good people are leaving for better paying industries,with better benefits, and better work life balances.
