Those who stay in school, actually educate themselves, and graduate. . . .those who stay mostly away from controlled substances and illegal activities. . . those who do whatever apprentice or odd jobs or part time work or take low end "Mcjobs" to learn a trade and/or acquire marketable skills, develop a work ethic, acquire references, etc.. . . .those who wait until they are married to have kids. . . .and those who are willing to start at the bottom in order to move up the ladder and/or get to the top. . . . . such folks will almost always earn a living wage and more.
One of the frustrating things about arguing with many liberals is that they think they are owed or entitled to a living wage among other things. They see it as their right for their employer to pay them that living wage regardless of how much their labor is worth. They see it as their right to have an employer who acts as more of a benevolent monarch providing for the people's every need. Of course many have been conditioned to look at government that way too.
Conservatives look at labor as just another commodity not any different than inputs, raw materials, infrastructure, transportation, or any other costs of doing business.
By the time you figure in waste, employee theft, inventory, and the cost of providing, maintaining, and making usable facilities, record keeping, plus mandatory licensing, taxes, and insurance, the profit on an Egg McMuffin or Quarter Pounder is pretty small. A huge volume is necessary to meet payroll and provide a profit for the employer who is risking a very large chunk of change operating that McDonalds.
Therefore, even in a very good McDonalds, the value of any one employee's labor is worth only as much as the price of product sold because he/she is there less all the costs of producing that product including a reasonable profit for the owner. Pay the worker more than the customer is willing to pay for the product and the business will eventually have to close and the worker will have no income at all.
Of course it is a two way street. Without the employees, the employer will also not be able to turn a profit and the business closes. In the free market, the employer and employees negotiate wages that serve the needs of both and still allow a profit for the employer. When that no longer is possible, there is no longer a McDonalds there.
Some of our more leftist/liberal friends here seem to think a profit should not be a factor in what the employees get paid.
