Recruiting normal people was cheaper and better.
In Attack of the Clones it was established that the imperial Storm Troopers were all clones of Jango Fett mass produced on the planet of Kamino.

Or the war effort needed so many that the clone factories couldn't keep up?
Where in the timeline did the Storm Troopers stop being Jango Fett clones?
