It takes 30 man-hours to build a car. It takes less than 1 man-hour to build a TV.
A car Made in the USA will cost probably 8% more, a TV maybe 5% more.
“It takes 30 man-hours to build a car.”
...the the rest of the cost is materials? Somehow I doubt they pay $10/lb. for steel, glass, aluminum, copper and plastic.
