I would add lots of kids in lower income homes are exposed to music being played by family members, peers, school programs, or church groups (examples). It's true that these kids might not be playing Mozart but there is nothing wrong with bluegrass, gospel, or whatever, to instill a love of playing music.

Maybe listen to "Juke Box Hero" or "Coat Of Many Colors" for inspiration on how people from modest backgrounds can have the same fulfilling experiences as wealthy people. (sorry - personal soapbox)
