One major way in which our system of federalism lead to conflict between the states and the federal government is that the federal government ultimately reigns supreme over the states--meaning that the states often feel that it is unfair to be subservient to the nation as a whole. 
The Constitution reserves certain powers to the states, but it expressly grants to the federal government the authority to act for the nation in many areas. The Constitution and federal laws are supreme, but implied powers are not named directly. Whether the federal government should act on these implied powers is a matter of debate.
