In educational theory and higher education literature you can make pretty direct correlations between politics and restrictions on education. Basically any time you say training is to time/cost/physically/etc.. intensive there is some political force at work rather than good educational techniques. Basically what I get from the literature of education is there is no such thing as to intensive. The second thing is that cost is truly relative when dealing with education. Spend more now and save over the lifetime of the entities involved. The fastest way to efficiency is to train harder and faster and more realistically.
