Right now they are profiting off of artificially low wages
No they are payng wages that reflect the skill level and the contribution employees bring to the business they work for.
In most cases they are, but in some cases there definitely is vulnerability issues where the temptation to exploit labor does arise, and is found on occasion. It best to punish the bad players quickly, and protect the good ones by doing so.
It is not possible to exploit employees who willingly agreed to work for an agreed upon wage.
People sell their labor to an employer. would you say a person selling any commodity exploits those who freely and willingly purchase that commodity ?
Of course it is when they have no other options
Low skilled workers have minimal bargaining power. Makes it easy to exploit them
But are they even being exploited?
As i have stated here, many if not the vast majority of min. wage employers have pretty thin profit margins. They can't just pull $$ out of their ass and pay 30%-40% higher wages. Your average Grocery story is making less than 5% margins. Fast Food can be less than that.
Where does that money come from?
The consumer.
And who is the #1 consumer of fast food?... low income.
