I don’t remember the last time a German athlete won a medal in track & field out of nowhere at the Olympics. The last athlete who did it was probably Nils Schumann and he was very fishy to say the least.
If you just look at the facts, then it is objectively the best decision for many athletes to dope:
a) How much will your standard of living/financial situation improve if you win a medal/gold at the Olympics?
b) How likely is it that you will be caught?
c) What will be the consequences if you get caught?
For someone from India, Pakistan, Nigeria, Kenya, Jamaica or Ethiopia it would be stupid/irrational not to dope.
All over the world there are people who are willing to risk their life to trade illegal drugs. Meanwhile people seem to think that athletes can be scared off by a possible two year suspension (if they get caught doping), when they have the chance to dramatically improve their standard of living by winning a medal …
If you want to stop doping, you have to increase the likelihood of dopers getting caught and you have to make the punishment (financially) more severe. You also have to hold countries accountable. Countries that can’t stop their athletes from doping shouldn’t be allowed to compete at the Olympics.
