Why would they have more power ? Employees have the power to say no, shop somewhere else, to do a shitty job / not follow orders and let the employer figure it out, quit when they want, leave the employers without the job being done overnight. They also receive something very defined and predictable (money defined in the contract) in exchange for some vague objectives where the employers needs to constantly check if the company mission is being fulfilled, and constantly update this mission.

   Workers need wages and money to survive in the economy

And employers don't need wages and money to "survive in the economy" ?

Not if they inherited it. The key idea here is asymmetry of power. When people are desperate enough that they would take a sub-minimum wage job, this doesn't necessarily imply a "voluntary exchange". If you're facing starvation or medical bankruptcy, you are essentially being coerced to take any job you can find.

If you're worried about people being in bad situations, why do you think laws that would prevent them from improving their situation is a good idea ? What do you do with those that are not in this situation, yet still interested in the jobs you judge not good ? How can you make that judgment for others ?
