Technical people understand how critical knowledge is to their survival.
Most likely they've suffered through a project where they didn't know enough, and the acts of discovery were painful. At any group meeting, within minutes of noting the need for training someone feels compelled to explain how it's too expensive and this particular period is not a good time to have the staff away from the office. Typically, this is spoken with such nervousness that you know that even if the training was affordable, having key people unavailable for any period of time would be stressful for those left behind. In today's high pressure environments, the combination of budget constraint and pure lack of time kill the chances of on-going, meaningful training. Direct opposition to the impossibility of formal training is futile.
