All the above need to be re-taught the ways of the REAL world. Experience is not what this is about. But laws, rules and practices are different and need to be learnt, understood and used.
you've got an odd attitude rigger, you've clearly identified the point, it's about things being different (see above), but you also bang on about the real world (see above). It's a fairly typical, I've moved on and am now better than you attitude.
Well done for moving on. I agree, that in some respects you've moved on into the real (commercial) world, but in many respects you've just moved onto something different.
