>Game design is a lot more rewarding than scientific research.

Doesn't this directly contradict you first comment?

>People should think for themselves and pursue whatever career interests them most.

There are certain skills that are considered to be necessary over others. Literacy is a good example. Math is another.

There are other skills that might have less of an impact than literacy, but have a direct impact on society and the quality of life for everyone. History and science are good examples here. History because being knowledgeable about the politics of yesterday helps in framing political decisions today. Science because our lives have been affected by (and improved by) science for the past few hundred years.

Having a populous that's informed about the benefits of science and technology and how they affect all of our lives should help everyone make better decisions regarding the two -- from a mom who mixes ammonia and bleach to clean her floor to the congressman who brushed off Vint Cerf's testimony during the SOPA hearing with a comment about nerds.

So, while we should encourage people to follow their passions and explore interesting topics, I'm comfortable saying that we should encourage certain things like math, reading, science, and history over game design, running a business, or basket weaving.

No one stops you from encouraging.
