"economic migrants" need almost zero training. However, I do agree that this will put pressure on already complacent welfare system, or group of people and may cause new economic, social regrouping, wealth distribution etc. To provide services, one would be incentivized to integrate.

It is completely possible to provide services without integration in insular communities, which tend to appear when newcomers come faster than they can integrate.

it's absolutely possible to spend whole winter in a thin cotton shirt, but most of us prefer not to do.

Only as long as one doesn't have a sizeable presence in the host country.

I disagree. Incentive to get recurring business mandates integration. Also, if the presence is not sizable enough, they would largely go unnoticed, so, integrate or not, it doesn't matter.
