Vancouver is experiencing a “renaissance of economic prosperity,” Mayor Tim Leavitt said during his State of the City address late last month.The big announcement was that another slice of Silicon Valley’s high-tech wealth plans to move to Vancouver. RealWear, a company making head-mounted tablets, signed a letter of intent with Fort Vancouver National Trust to open offices in the renovated Artillery Barracks.“The work we’ve done over the past decade has positioned our city well for future growth and development,” Leavitt said.However, he acknowledged, work remains on addressing homelessness and affordable housing. A few days prior, The Council for the Homeless announced that street homelessness was up 18 percent from last year. At a Vancouver City Council meeting, people hotly debated how to deal with the blight of homelessness downtown. (Vancouver has not yet seen benefits from a 2016 voter-approved levy intended to generate more affordable housing.)Vancouver, and Clark County at large, are experiencing extremes that can be measured in the widening gap between rich and poor. Celebrations around an influx of high-wage jobs contend simultaneously with tensions around homelessness, housing affordability and poverty.“The income has gotten more unequal in Clark County in the last eight or nine years,” said Scott Bailey, regional economist with Washington’s Employment Security Department.Bailey analyzed Census data by running the bureau’s numbers through an inflation calculator to see how changes in income are impacted by the increasing costs of things.
