[DC] Before its destruction, did the average Kryptonian know that they'd get superpowers under a yellow sun?

Or was it just something that Superman found out when they sent him to Earth? Like, were they teaching this stuff in Kryptonian science class? Why didn't the Kryptonians make efforts to colonize worlds with yellow suns?

They knew, but they were technologically advanced enough that they didn't really care.

It seems cool to us to be able to jump tall buildings in a single bound and things like that.  But why bother if you already live on a paradise world with super-technology?  If you want to fly, you can just strap on an anti-gravity belt or something.  No need to move to some crappy planet where they don't even have gold volcanoes or flying houses.
