Can anyone suggest how Americans generally view the partnership with other states?
Does each state have a strong collective identity, or is it rarely expressed? Is the sense of membership of the USA always stronger than towards individual states?
For example, is there any obvious disquiet about the disproportionate contribution to the economic situation that somes states seem to have contributed?
