LDR working man drag radial class

Was just on FBBO and read about a new radial class for the working man. Said they expect cars to run 4.20s in the 1/8 mile. This is a working mans class? Holy crap I need a new job. What average working man can afford to build a 4.20 car. Are we talking 50 to 100k for a car that's competitive. I must be out of touch.
