You all should be doing more to attract minorities vis a vis very generous welfare programs. You know, free shit.
Your suggestion is very simplistic. Not surprising, most folks don't bother looking into the details of these issues and resolutions before they offer their opinions. It takes more than generous welfare programs to create racial and ethic diversity in an area.
For example the Oregon housing authority has a rent voucher program for people who meet the low income qualification. To use the voucher there has to be affordable housing. I just checked Zillow, there are very few places for rent in West Linn at the moment. The least expensive is $1,200 a month for a 2 bd, 1 ba 850 sq. ft. apartment.
https://www.zillow.com/homes/for_rent/ Oregon also has a Supplemental Nutrition Assistance Program (SNAP) which anyone who qualifies can apply for regardless of where they live.
The same is true for the Oregon Health Plan (OHP). OHP is free health coverage from the State of Oregon for people who meet income and other requirements.
In order to qualify for Temporary Aid to Needy Families (TANF) a person has to be unemployed or under-employed and have at least 1 dependent under the age of 18 or is pregnant.
That there isn't available affordable housing is a Statewide problem. It is one of the reasons for our high incidence of homelessness. There was a recent article in the Oregonian about the lack of affordable housing despite a multi-million dollar Federal grant. Although, the money was provided several years ago, hardly any of it has been used.
The problem is that construction companies aren't interested in building affordable housing because there is so little profit in it as compared the profits from high end housing. If I remember correctly, only one public housing project has been built in Portland so far.
