The government should not be in the wage increase business. You are paid for what you bring to the table. The individuals that are in these jobs, should use these jobs for what they are, an item on their resume when they were teenagers. These type jobs are not career jobs.
If you want a job that pay more, you would need to get an education or learn a trade that would place you in a position to offer an employer job skills that demand a salary based on the skills you bring to the job.
Instead, you want the government to mandate an employer pay you a minimum wage.
Mandating a salary minimum, would put many mom and pop operations and small business owners out of business. Their bottom line would not permit them to pay this increase in wages for these unskilled workers.
Also eventually technology would catch up with you, thus you would be unemployed. Currently the fast food industry is bringing on line computers and robots that would do the mundane jobs of a fast food worker. These robots have been tested and are able to prepare any order placed. Eventually these jobs will no longer be available. Now you will not have the mandated increase in pay, you would be out of a job.
The good thing about robots is they are always at work, never make a silly excuse for taking a day off from work, like my grandmother died for the 10th time or my baby is sick, my car did not start. They do not complain about the working conditions and the management team.
The show up on time in the proper uniform with no attitude.
I am oppose to the government mandating an employer is required to pay their workers a certain amount each pay period as I am to a union that want to pull a chair up to the table and eat and have no vested money or time into the business. Unions are leeches.
I hope this has been of some benefit to you, good luck.
