Is there a euphemistic word for "of or relating to the bottom socioeconomic class"?

Can someone provide an adjective that means "a poor man's" but doesn't possess any negative connotation?

For instance:

Crack is the (poor man's) cocaine.

Solution 1:

There are numerous phrases for this in the field of social policy. I believe the current one is disadvantaged:-

lacking in the basic resources or conditions (as standard housing, medical and educational facilities, and civil rights) believed to be necessary for an equal position in society [Merriam-Webster]

but they change very quickly and I don't pretend to keep up. So you sentence might read crack is the cocaine of the disadvantaged.

Solution 2:

How about disenfranchised?

Apart from its more technical denotation, it can also be used to describe a voiceless person within society; someone who for various reasons does not have a say in society at large.

I think it safe to say that poverty can be an implied companion of disenfranchisement, but not necessarily. Sometimes a person who is relatively well off can be discriminated against for reasons having nothing to do with their economic standing in society.

Still, disenfranchised can pass muster as a euphemism, I suppose.

Solution 3:

underprivileged, on the breadline, disadvantaged, necessitous.. these words are not completely euphemistic but are somewhat lesser in degree than poor.
