What if the US had Germany’s codetermination laws?

Particularly the One-third representation act and the Co-determination act ?

What if the tie-breaking vote came from the employee side instead of the shareholder side ?

I’m not sure how talking about this in terms of having both a supervisory board and management board or having a single board system like the US typically does would impact the discussion.

How would you predict this impacting the US economy ?
How would you think this would impact labor-management relations, long term investment (of the companies), inequality between executives and workers, and profitability and efficiency ?
