>It could be that US investors are less willing to invest in co-ops. But then, why? Is there something about them that makes them less competitive?

My, admittedly uninformed, guess would be it has to do with 1) there are more worker protections in the EU than in the US and 2) Co-ops tend to pay employees better wages, have better benefits, etc.

Shareholder corps will try to drive down their labor costs as much as possible. Walmart goes so far as providing advice to how it's employees can best apply for food stamps, all the while keeping them under the 32hr/week threshold that would require them to receive benefits. This can provide a price advantage against co-ops who are not running these same practices. It the EU the labor protection laws are better so the potential difference of labor cost is diminished between sharecorp and co-op.
