Doesn't this happen everywhere? People who can't afford to live in certain neighbourhoods move to neighbourhoods they can afford. Businesses follow to meet the needs of the "newcomers". Are the newcomers at fault for buying / renting homes in neighborhoods they can afford? Do the older residents of the neighbourhood have exclusive control over the  cultural makeup of  the neighbourhood? Perhaps they should adopt a policy of not renting or selling to the intruders - I believe some Toronto neighborhoods had an unspoken rule that you didn't sell to Jews way back when (Rosedale, Forest Hill). This is just the same kind of racism re-packaged to fit the "cultural appropriation" narrative. So what if a white person opens a restaurant that plays to the history of the area, even if it is an innacurate portrayal. Chocolate chip bagels are a bad example of cultural appropriation, this issue is simply about people who are getting priced out of their neighbourhood. Too bad, it happens everywhere.
