This experiment was done in Israel - I wonder what would other countries would look like. Israelis seem to be more aggressive and creative in getting what they want than, say, Southern Californians.
This is a valid point, and I can only assume you are being downvoted due to "stereotyping." The sample group IS an important factor. For example, Milgram's famous "electric shock" experiment was repeated in many different countries. Germans for example, were very susceptible to authority figures, Australians were lesser so. Results are going to change based on the group being tested. It still doesn't change the fundamental finding of the study, however.
Probably more relevant to say this experiment was done on college freshmen, but yes, it would be interesting to see differences by country/etc. provided you can provide uniform experimental conditions (at a minimum, keep participants in the dark as to the composition of the experimental group, the fact that it's being done worldwide and comparisons will be made of their nation vs. others, etc).
