Fashion takes work...too much work, in my opinion. Perhaps you say this because they both drink lattes?
While I don't think that these sorts of stereotypes are terribly precise (or incredibly useful), it is sort of interesting that younger generations seem to be lumping together gen-X-ers, hipsters, and Holden Caulfield together under the label of "entitled". If you ask me, the current generation of college kids are far more "entitled" by any conventional definition, so it's a curious choice.
Now get off my lawn. :-)
hipsters wear flannel shirts and tight jeans.
slackers drink Grain Belt Premium.
hipsters drink PBR.
slackers smoke marlboros.
hipsters smoke parliament lights.
slackers listen to pavement.
hipsters listen to MGMT remixes.
slackers have jobs but don't do any work.
hipsters don't have jobs at all.
by definition if you have an engineering degree and are working on your startup or at google you aren't a slacker or a hipster.
get it straight.
