Big companies will have no problem with these regulations. However small and medium sized companies need a bunch more busy work that needs to be done and so will avoid it.
This last is hard to measure - regulations have a cost in this form but it is hard to figure out what would have been done but isn't.
IMHO, the US should have much more "larger than X" laws (and clauses that enfold organized subcontractors working for larger corporations).
1. Companies do weird divisions to keep under the limits
2. Companies are artificially restricted in their growth as they need to add employees but are unable to, for example if the cut of was 50 employees, adding the 49th employee is easy, adding the 50th employee is $$$$$ thus it will not happen, this would mean few companies grow to 50, rather you would see several 50+ employee companies merge as the cost burden for the new 100 employee company would spread over all 100 employees, vs the regulatory cost being hit with the single employee add
I am not sure why you think anyone or any company would DESIRE to have external actors imposes requirements on their actions or why it would be unpalatable to say you do not want to have regulatory burdens imposes on you
As a culture have we so lost the respect for freedom and liberty that is now bad if you want to have said freedom?
Of course they desire to have external actors impose requirements on their own actions and other people's actions and other companies' actions. Just so long as they think those requirements benefit their bottom lines.
Ever hear of the business lobby opposing union-busting laws on the basis that they create regulatory burden?
In a choice between maximizing efficiency for good actors, and curtailing behavior by bad actors, I tend to weight the latter.
A) Companies oppose regulation because of filing and compliance costs, despite already doing the required behavior
B) Companies oppose regulation because they don't want to have a requirement to do and maintain the behavior
It feels like really we're talking about (B) as a primary motivator, and (A) is a smoke screen for PR palatability.
