I’m not sure if you’re meaning why our regulations are worse, or why our working environments are worse. The first is because the rich have done wonders capturing our politicians so they can capture our media so they can manufacture consent to allow people to be willingly crushed by the machine while people are too exhausted by the system to organize and fight back. The second is caused by the first, and also helps reinforce the first because so many of us are temporarily embarrassed millionaires who would blow a blood vessel if those who didn’t deserve it got help (but they’re different and totally deserve it).
