Apprenticeship Ratios Update

I've been on a learning curve about these ratios. The link below is to a Connecticut based research article that seems to indicate fair uniformity for electrical, plumbing and HVAC trades. They typically start out 1:1 for a self employed tradesman, 2:2, 3:5 etc. For greater numbers, the ratio becomes 3:1.

End result? Big contractors need to hire more journeymen as they grow. The panic has started recently as journeymen get older. What hasn't happened, is wages increasing very much. 

How widespread of an issue is apprenticeship ratios? I like to hear about it.
