Intellectual or social class?

Does "intellectual or social class" mean "intellectual or social elites"?

Background info:

The author insists that the mentally ill are not inherently different from any of us.
Schizophrenia favors no intellectual or social class; it can strike anyone. Saks has
worked for years advocating for men and women with psychological illnesses, and
she wrote this brutally honest book partly to make a public statement that no one
suffering from any disorder, mental or physical, should be stigmatized. Saks sheds
light on the ways in which schizophrenia afflicts young men and women, robbing
them of everything that they need to take their place in society: an education,
normal relationships, and a profession. Unfortunately, most schizophrenics do not
have Elyn Saks's intellectual, emotional, and financial resources, nor do they have
her strong support system. However, with ongoing research and more effective
drug treatments being devised every year, there is hope that this heartening
success story will someday be the norm, not the exception.
