Where to start...
Leftists do not appear to understand what a "corporation" is. It is a FICTITIOUS person, created by the state, at the request of an investor or investors. The reason for its creation is generally revealed in the articles of incorporation, but the corporations in question are created for one purpose: to make money for the investors. Period. They are not created to be kind or generous, or to be "good citizens."
The officers and managers and employees of a corporation have one overriding goal: To protect the interests of the Owners/Shareholders. To make them money, and hopefully increase the value of their investment.
They make money by providing desirable goods or services to people who want them, at a price that is greater than the cost to produce them, thus rendering a "profit." EVERY SINGLE CUSTOMER of that corporation believes, at the time of purchase, that the value of the goods and services is greater than or equal to the price paid. Otherwise the customer is an idiot.
So consider the hiring of an employee. Say the corporation requires someone who can use sophisticated equipment to apply paint and other coatings to their products. And say that this skill can be learned by a reasonably intelligent person in a couple of days. If the corporation can find such a person who is willing to work for $10/hour, why would it pay $10.01? Or more?
The corporation doesn't care if the prospective employee has school loans, has a family to feed, or lives under a bridge - nor should it. And if it CAN'T find someone acceptable to work for $10/hr and has to pay $12 in order to get the people they want to apply, the corporation will do that. Or if it finds that people hired at $10/hr tend to be lazy, unreliable, or accident prone, then they might decide to pay more and raise their standards. It is neither good nor bad, it just is.
Leftists think corporations should be obliged to be "kind" and "generous" to their employees (and to their customers). They think that corporations should BE FORCED to pay a "living wage." But this is literally stupid, as well as counter-productive.
Employment is, in the private sector, an entirely voluntary affair. EVERY SINGLE EMPLOYEE has made the decision, whether s/he thinks about it overtly or not, that THIS PARTICULAR JOB is the BEST THAT S/HE CAN DO at that given time. If there were a better job available, s/he would take it. And the employer has decided that this employee is worth the money it pays; otherwise the employee would be replaced.
IT IS AN ENTIRELY VOLUNTARY ARRANGEMENT. To say that the corporation should pay more because some outside agency believes that the wages are "not enough" is just silly.
But then, Leftists are silly.
