No we're not in this together: it should be obvious that people and places with more resources fare better

 A couple articles in the Washington Post start with the argument that an exogenous event like a pandemic should be a great equalizer between the well off and the impoverished.

-- "A pandemic should be the great equalizer. This one had the opposite effect"
-- "Not even a pandemic can break rich cities’ grip on the U.S. economy"

You don't have to be a Marxist to understand that's not how the world works in capitalism.  

People with more resources do better than those with fewer resources.  (An easy way to figure this out is to read the weekend sections of the Wall Street Journal and the Financial Times, and the Friday Mansions section in the WSJ, the lifestyles portrayed are nothing like how "regular" people are able to live.) 

This is most pronounced with health care outcomes such as life expectancy ("The Association Between Income and Life Expectancy in the United States, 2001–2014," Journal of the American Medical Association, 2016).  Members of higher income households tend to live almost 15 years longer.

Concerning the pandemic, people who have more resources have health insurance so they don't stint on going to the doctor, can withstand gaps in income from hospitalization or quarantine, live in less crowded conditions, etc.

Similarly, cities and metropolitan areas with more resources do better than those places with fewer resources too.  Metropolitan areas do better than rural areas too (" Getting Health Care Was Already Tough In Rural Areas. The Pandemic Has Made It Worse," NPR).

Although some areas can be more vulnerable than others, depending on the nature of their advantages and if their economy is especially concentrated and homogeneous--for example cities like Houston and Tulsa are vulnerable to downturns in the oil industry ("I get tired of the articles that ascribe Houston's economic success to its lack of zoning" and "A follow up on an earlier point about Houston and extractive economies"), and how Michigan was once the center of the US-based automobile manufacturing industry.

Or, at least in terms of manufacturing, Greater Seattle and Boeing, and Boeing's decisions over the past two decades to move away from Seattle because the jobs are unionized.  The company moved its headquarters to Chicago in 2001 ("Inside Boeing’s Big Move," Harvard Business Review) and has been decentralizing plane manufacturing to Wichita and Charleston.  They've just announced that all 787 plane production will occur in Charleston. ("Jilted again, the problem isn’t Boeing, it’s us," Seattle Times).

Although many argue Boeing's moves destabilized the company's core competencies ("How Boeing Lost its Bearings," The Atlantic). 

And even when earthquakes or other natural disasters occur, people with more resources tend to do better, the less well off live in areas more prone to flooding etc. There are studies about how the rebuilding effort in response to hurricanes stokes the local economy, although those studies don't fully take into account the economic losses.

But it's pretty clear that low income households (and poorer areas) suffer disproportionately.

Although if "crowding" is something that has to be avoided for many years as a result of the pandemic, the "competitive advantage" of cities -- agglomeration -- is wrong-footed.  

While I believe that over time, with vaccines and other changes, cities will come back from the current situation, where office districts are ghost towns, with the resultant decline in businesses and cultural spaces of all sorts, it will come with great pain in terms of closed up businesses, empty buildings, and a massive revaluation of commercial property.

This is separate from the issue of too much space devoted to retail and the impact of e-commerce on physical retail, both of which has led to a shrinkage of many retail chains, and the continued bankruptcy and dissolution of companies--for example Neiman Marcus has shrunk and Lord & Taylor, the oldest department store group in the US, is shutting down.  Although the pandemic has accelerated this process.
