Class war?
As long as a society has people with very different circumstance(for whatever reason) and certainly this society has groups in wildly different circumstances, then social policies will effect those different groups differently.
That's just the way it is.
xThe most significant element that determines "CLASS" in this society, is based on individual and family wealth.
Protesting that ours is a "classless" society is just so much nonsense
Historically, 'class' based societies were those that one was born into a certain societal structure and one could not move from that class. .
Nonsense. You're confusing CLASS with CASTE, CG.
No society ever devised by man can exist without different classes of people.
Now how one determines what class one is in depends on the value system of your society.
Here in the USA, where there is no formal caste system, one's class is primarily based on one's net worth, one's family, one's education and one's job.
When we discuss how tax policies might effect people with very different incomes, we are discussing how those policies effect different CLASSES in terms of wealth.
