As an independent Asian american (non Indian/Chinese origin), this is my humble observation based on time i spend working with open source products/community. Most of the open source products / projects are initiated and mostly contributed by the white Americans. Although this is changing i still see the trend in most of the open source projects such as openstack/containers etc.. Asians are mostly focused on the financial aspects of the projects/products and therefore fair bit of entrepreneurs and startups.
When it comes to who works hard and who doesn't, it is a mix bag and mostly depends on the individual.
