No doubt that it's not "only low wage workers losing their jobs". However, it is far more likely that we are seeing a disproportionate amount of job loss in the "low wage" category. Without formalized statistics, the vast majority of job losses so far have been in the front facing service sector (retail, restaurants, bars, airlines, hair dressers, etc....). These groups represent a much larger percentage of the overall population, than they do the DVC Owner population. As
@CraigInPA was suggesting, until the economic fallout from all of this starts having a "major" impact on the job security of the upper middle class (which I would expect to be the vast majority of the DVC population), there likely won't be the fire sale on DVC contracts that some are expecting.
What you may be seeing is sample bias. I don't know your personal situation, but most people tend to socialize in similar economic circles as their own situation. If you fall into the "middle class", you likely are socializing with others in the "middle class", therefore those job losses are being magnified.
