Pot shops driving out other businesses? Not like you can sustain several per block. More likely a pot shop is a symptom of already advanced gentrification.
Regarding this specific idea that the pot shop reflects already begun gentrification, I think there is evidence both ways. Regarding the argument that there is a limit on how many the neighborhood can support, some of it would take too long to go through, and all it would get is disagreement based on people's various leanings. In any case, Ike's specific location was vacant for an extended time before he moved in here. Mainly because it was awfully easy for anyone who opened shop here to wind up dead in his store. The last guy was a young African immigrant with a family who was shot during a late-night robbery of his restaurant.
In any case, this train is long gone from the station. The true center of African American life in Seattle is far to the south in Rainier Beach. The CD in Seattle has a much higher white precentage than for example Manhattan.
Interestingly, this area prior to WW2 was largely well to do upper middle class families in large houses in the westernmost area (closest to downtown), and Asians farther to the East. Boeing's big worker ramp-up brought in people from all over the US to build planes, and the nearby CD was one of the few or perhaps the only place where those who might have been locked out elsewhere could freely move in.
After the war, many of the Japanese returned to this area after being released from internment. Many moved to Mercer Island and more suburban areas.
BTW, Eisenburg is an excellent businessman. This one store grossed over $25kk since opening in 2014. The locus of young well paid tech workers is South Lake Union near Amazon, and Capitol Hill from where it is easy to get to Amazon, downtown tech, and the Microsoft Connector or the bridges and public trans to Redmond. Uncle Ike runs nice stretch SUVs from these tech enclaves to take customers to him a few blocs to the south and east.
Last Wednesday I was riding with a driver that I often use, to go to a restaurant in the Salmon Bay area of Ballard. He has been driving around here for years, and he says that when the big Amazon ramp-up in So. Lake Union got going for real, the formerly hot residential area of Belltown just had population sucked from it to So Lake Union.
Demographic change is less certain than say hurricanes in the Southeast, but It is is basically inevitable.
