Working as a Tech myself, this is pretty much exactly what I was going to write. I completely agree. Sometimes I do a 4 hour job in 1/2 hour and make great money but other times it's a 1/2 hour job and takes 4 hours and I loose my ass. Seems like shops are raising prices and paying techs less. Techs used to see close to 50% of the labor rate. Nowadays your lucky if your seeing 20-30%. And like Jasper metioned. There's a huge tool investment . I'm well over 100K myself. Like mentioned earlyer . You only get R&R time for the most point but theres lots of time involved in testing, cleanup, racking, writing , etc etc...
