The other side of this coin is maybe if there was less uniformity and less federal law pre-empting state authority, massive multi-state corporations wouldn't have as much power and control. We can take the EPA vs CARB as an instructive example. EPA regulations pre-empt federal law, and California gets a specific, expiring exemption to have stronger regulations. But maybe emissions regulation could be even better if more states with like minded people were able to pass stronger regulations like California. Certainly one wonders why only California has such an exemption given the apparent popularity of stronger regulations.
