First of all you can't deduce logically that the reason people use EMS as a stepping stone is because of the inherent faults in the EMS system. The reality of society today is that the average length of stay in a job is now under 6 years. Jobs change, careers change, people move, get married, have kids, divorce, move, change careers....
There are those who choose a linear life. They pick a career, follow that career until retirement advancing to the highest level their ambition, intelligence and emotional satisfaction will take them. Others follow a more meandering path. I know of a P.A who started out as a flight instructor, a nurse who began her career as a high school chemistry teacher. I have a dear friend who works as a botanist who graduated with her Masters Degree in classical spanish literature.
To insist that everyone follow the linear path and that young people with no life experience make final, unalterable decisions regarding their future careers is unrealistic. I've followed the stepping stone path through my life with employment in hospital purchasing, accounting, printing, I managed an Art Gallery, I worked in the labor movement as an organizer, I even waited tables. I was able to find financial stability, raise two kids, pay off my house and put money away for a retirement.
Do I care if my personal life choices make those who are more linear uncomfortable? Not at all! I work hard at whatever job I am in and do well within it. A personal work ethic is going to make you do well in a job whether or not you do it for months, years or decades. A long time in a job can make you excel or stagnate depending on how you spend your time there.
So I raise my glass :beerchug:to those willing to move on, change roads, switch horses in midstream. to boldly go where they have never gone before! Hooray to the unconventional! EMS will survive our presence in their midst. Every other career has!
