It's been demonstrated over and over again that building high end housing does have an impact on the prices of lower end stuff.
It is of course likely to have a greater impact to build lower cost stuff, but blocking a development because you don't like the sort of houses they want to build is more or less stupid (it's not like a developer is going to do a project there is no demand for, and that demand is probably already looking elsewhere near the proposed development...).
