To me, the bottom has, is, and always will be "the struggle". Having to overcome or do without. If you're talking from a character, image, and personality standpoint, Drake has come from the bottom in a lot of ways. Having the woman you wanted to wife turn you down because of your corny image is struggle. Dealing with prejudice because of your unconventional upbringing and background is struggle. Making a serious musical push independently is struggle.

If we're talking socio-economically-- and not socially-- Drake did not come from the bottom. But if we're talking strictly from a social standpoint (Jewish, identifies hip-hop/urban, Canadian, unconventional (initially) musician, *gasp* a colored boy that didn't grow up dirt poor) then he did. 

I know people that live in lower-class environments, yet amass upper-middle class money and power. I don't consider them from "the struggle". On the other hand, I know people who live in lower-middle/middle-class areas that break their backs trying to live the "American Dream". This is why I don't like certain cities in America that have high cost of living, because average people live next door to the bottom feeders and brag about being from that cloth based on being IN the environment, but they are not actually PART of the environment aside from living close by people that really don't have much.
