Answer:
The cultural lag describes what actually takes place in the social system when the ideals that governs the society are not able to keep pace with the advances that are most of the time, but not actually always the technological advances. There norms are life support, stem cell research and findings, and cancer vaccines when we deal with American society, which is quite the fastest to keep pace with the technological advancement in general. Its possible now technologically to keep a person alive than he normally lives, but society still needs to accept this. The others are similar, and hence the other two norms. United States is a developed civilization, however still the life after death has not been accepted, however, extended life is definitely a possibility now. Its is quite expected however that soon it is going to be accepted. Hence, its a matter of time only, but since it has been not accepted till now it is a cultural lag. Stem cell research is also a similar situation. But soon it will be accepted as well. Hence, US can be supposed to be the most advanced society, and the above cultural lags are for the time being only, and soon will be accepted. None of the other countries, you can expect these to be accepted currently. That is why US is the most advanced society of the world. However, some ethical conflicts and crisis still exist, but it will be removed soon, which is expected.
