This is a gross generality and certainly not true across the board. I obviously can't speak of all neighborhoods, but here in Chicago white/Europeans were displaced prior to the 70s in many of the neighborhoods that are now undergoing or have undergone gentrification. In the 60s, for example, Poles were the predominant ethnic group and Puerto-Ricans went from comprising only 1% to 39% in a handful of years. Why? Freeway construction. As a result, gangs took hold and it was a crummy place to live that had nothing to do with crack or racism, at least not directly. The situation was similar in Humboldt Park where in 1960 it was 99% white and by 1980 it was only about 30%. Same situation in Pilsen when hispanics displaced whites due to construction of the current UIC campus.
There are a number of reasons why these areas were impoverished, crime-ridden cesspools around the 70s. And racism does certainly play a role on some level. But let's not act like in all these currently gentrified areas they were once stable, safe, and economically sound ethnic neighborhoods that were poisoned by the white man introducing crack. Drugs and crime are a symptom of poverty. Neighborhoods didn't turn that way because of sabotage, but because when the hands were changed racially the wealth disappeared and the city didn't and still doesn't give a shit about investing in poor areas.
Fair point re: Chicago. For the DMV (DC, Baltimore, VA), this wasn't the case.
To the second bolded point, I think that's the basis of a fantastic conversation. I believe that on a societal level, we've been taught to operate under the belief that the correlation is Drugs and crime are symptoms of poverty.
In the past few years, I've been personally redefining what 'poverty' and 'wealth' actually mean. If we're defining poverty as a very specific socio-economic income bracket, and, for the sake of conversation we'll say that the average income level for an area is 15k, then I challenge that lack of access to resources and opportunity creates poverty and crime, and not actually the income disparity between the classes.
So here's a thought: hypothetically, you take an area where the residents make less than 15k on average. However, local government keeps the neighborhoods clean. Public transportation is plentiful, very clean, safe, and highly affordable. Instead of liquor stores, affordably priced grocery stores are at the ready.
There are numerous after school activities, job and career assistance programs for teens. Police, firefighters, and politicians play an active presence in the community, serving not only as cold adversarial watch dogs, but as active and interactive big brothers REGULARLY visiting schools, participating in curriculum, and allowing teens a peek into the lives of healthy, working, transparent, public servants.
Communities are incentivized to do things like inner-city community farms. While the big box stores like Best Buy and Walmart aren't around, smaller, community-rooted stores are also incentivized by hearty tax breaks, circulating dollars within that community.
Not to mention 'community fare days' which are plentiful in economically thriving areas. Towns have all sorts of community gathering days, and here in Torrance (for example)I'm constantly fielding calls from government officials polling me about ways to beautify some area or if the political officials were visible, responsive, or active enough to my tastes.
Imagine this government-assisted community where these people, although making lower wages than their neighbors across the tracks, are living a life with the SAME potential for possibility? The same feeling that of community ownership and pride.
Do you REALLY believe that this 'poverty assessed' area would be rife with crime and drugs?
Me neither.
Less money doesn't have to mean 'worse off'.
