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.

I don't know much about Andre's strength feats. Was he exceptionally strong? Wrestling definitely involves lifting heavy opponents, especially in Andre's weight class. So, if he was extremely strong, I can see why despite no explicit resistance training, given his wrestling and increased HGH.
Yeah, this whole discussion is based on assuming human genetics. Every animal, without any resistance training, will develop an amount of muscle within some range. This can be massive, like for gorillas. Perhaps someday we will have gene editing that allows us to have the muscle building genes of gorillas, so we can all bench 1,000lbs with no training.
I wonder, do gorillas possess the mechanism for stimulating muscle growth via resistance training? How strong could one be with a dedicated training plan and coach?
It certainly does not need to be painful. I think most people will make a distinction between the burn of acidosis, or what you call unease, and actual pain indicating damage is occurring.
But yes, if you never train close to failure you will not grow, not past beginner gains, unless you take steroids.
