I believe the answer is keynesian economists
Keynesians' view was heavily influenced by John Maynard Keynes, which advocated many forms of Government intervention in order to achieve full employment in society.
Things such as welfare, taxation increase,and housing assistance, are examples of Government intervention to allocate wealth from the rich to the poor
So a social group is a group of people that share similar characteristics. And they are important because it gets you to interact with peers. The last question is one you have to answer on your own so I play baseball and I am a Highschooler so therefore two Social Groups for me would be Baseball, and Highschool
I hope this helps :)
