Cultural consequences do not assume to lead to cultural heterogeneity only. All cultures accept outside influences all the time. Some external influences may be negative even to reduce our choices. Sometimes external influences enlarge the choices or modify our culture without overwhelming the traditions.
i. e. the burger is not a substitute for a masala dosa, blue jeans can go well with a homespun Khadi-Kurta (a unique new combination by external influences). Hence, it can be said that globalization does not lead to cultural heterogeneity every time but it is supportive to promote cultural outlook and cultural homogenization.
