I think both things are true. There is a lot of regulation surrounding labour and employment that was hard won by labour, but you're right that there is also a lot that was similarly fought for by the employers. This is part of the asymmetry of power -- as employers pockets get deeper, they are more easily able to have regulations implemented that further deepen their pockets. The same would be possible with labour, but there's little concentration of power there. It's a lot easier to spend $1m as a company to get the regulations you want than it is to organize however many workers to spend $1m to get the regulations they want, especially since no one will have the exact same regulations in mind.
