It is said that the average college graduate earns 1 million

It is said that the average college graduate earns $1 million more in his/her lifetime compared to an average high school graduate. Would this mean that if we forced all high school graduates to attend college, we would be able to raise their average lifetime income by $1 million?

Solution

THE AVERAGE INCOME OF GRADUATE IS 1 MILLION MORE THEN THE AVERAGE INCOME OF SCHOOL GRADUATE AND THIS WILL MEAN THAT EVERY SINGLE COLLEGE GRADUATE WILL EARN ON AN AVERAGE ONE MILLION MORE THEN THE SCHOOL GRADUATE. BUT WE CANNOT SAY THAT IF WE MAKE THE SCHOOL GRADUATE TO GO FOR COLLEGE GRADUATION HIS LIFE TIME INCOME WILL INCREASE BY 1 MILLION BECAUSE IN THE 1ST STATEMENT WE ARE COMPARING THE TWO GROUPS AND THE 2ND STATEMENT WE ARE COMPARING THE SAME PERSON IN DIFFERENT SCENARIO.
