I disagree that this song is about drug use. There are only a couple of mentions of drugs. The primary message of this song is an indictment of consumerism. Consumerism thrives on constantly purchasing things. She talks about all the shops in which to buy things. And the line, "To me what you say I need is just so unnecessary," indicates all the advertising that goes with consumerism, constantly telling people what to buy and to think.
The endless cycle of purchasing and advertising drains natural human experience and reduces all things around us to the numbing meaninglessness of money. That's why she says we're already dead.

My Interpretation

I was thinking a little further about this. If we stick with the idea of consumerism, then Generation N E Y probably stands for Not Enough Yet.
Also, this song talks about the determination to maintain ones' own integrity in a highly consumerist society.

I considered the possibility N E Y is meant to be heard as "any why" derived from "any reason". The idea that people mindlessly purchase useless garbage for no reason at all, and no longer think for themselves.
