Why is the British Government trying to trick youngsters into becoming Scientists?

Recently there have been lectures in my cl about how there is more to being a scientist than working in the lab and that sort of stuff along with leaflets on the lab walls. I found out the Government was launching a new program to encourage students to enter STEM (science, technology, engineering and maths) careers, by saying become an engineer and you could design racing cars but isn't science supposed to be a pion ,you never heard albert einstein want to be a footballer until he heard he could become the greatest physicist ever or Marie Curie a hairdresser until she realised she could discover radioactivity, the best scientists had a pion for STEM subjects, so why try to get those who don't have a pion, even if there is a shortage of scientist, engineers and mathematicians. Darn that was a lot of writing.
