The tenth amendment reserves any power not specifically granted (EXPRESSED/WRITTEN in the Constitution) to the federal government for the STATE government such as issuing licenses, determining speed limit, or drinking age. State governments were allowed many rights. However, this Supreme Court Case created INCORPORATION.
What is Incorporation
The Supreme Court previously held, in Barron v. Baltimore, (1833), that the Constitution's Bill of Rights applied only to the federal government, that states were free to enforce statutes that restricted the rights enumerated in the Bill of Rights, and that the federal courts could not interfere with the enforcement of such statutes. Gitlow v. New York partly reversed that precedent and began a trend toward its nearly complete reversal. The Supreme Court now holds that almost every provision of the Bill of Rights applies to both the federal government and the states.
