Then you need to pay attention to what the 10th actually reads:
The powers not delegated to the United States by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to the people.
Notice the peohibition thingy?
We are schmart.
I recognize that there are many things explicitly relating to states in the constitution. The problem is the federal government reaching into things under state control according to the constitution.
Commerce Clause\Necessary and proper\Taxing Spending- Funding clauses.
for instance: Article 1 Section 8 clause 3
Congress has power to regulate commerce with foreign nations, and among several states, as well as with Indian Tribes
states can't regulate commerce. (course, try and take fruit to and from california\arizona)
Course, Congress has abdicated so much and the Judiciary has made so many laws, being a strict constitionalist has no meaning.
