I don't think immigrants make up the basis of the Swiss economy. Looking at their demographic data[1], it was pretty strongly European dominated for a very long time, and is still ~80% European.

When people talk about immigrants in this context, I don't think they mean people from the US, but lower socioeconomic asylum-seekers and refugees etc. from the middle-east.

It definitely seems their economy was built on European labor, which I believe the vast majority of European countries were.

It depends somewhat on the specific campaign but generally in right-leaning Swiss politics, "immigrant" includes Europeans as well. I think that's definitely the case in this initiative since the text of the initiative requires ending freedom of movement with the EU.

They really don't like asylum seekers either though. Several of their arguments reference asylum seekers specifically: https://nachhaltigkeitsinitiative.ch/argumente/
