Congress has set a COLA into their own wages because they realize the cost of living generally goes up.
In the 80+ years of the minimum wage, every time it was raised, the cry of prices going up and jobs being lost has been heard constantly. But did you ever notice that prices continue to rise eben when the minimum wage stays the same? Compare, for example, the prices of everyday staples in supermarket ads from 2007 and current ads. Using the logic that minimum wage affects price increases shows otherwise. Housing Goes up, utilities go up, cost of food and clothing goes up.
When the minimum wage was established, it was to provide the basic wages needed to provide the basic needs. Bad Congress worked a COLA into it in the 70s like they did with Social Security payments, this argument wouldn't icvur every four to ten years.
The only way that the bencarl for minimum wage could be held would be price freezes on everything. I mean everything. All wages would have to be frozen. Gas stations couldn't play with their prices like they currently do. Electric, natural gas, telephone, never change.
Businesses raise prices because their cost of doing business keeps going up. Raw material goes up, advertising goes up, rent skyrockets, utilities, so why shouldn't labor.
Until businesses realize that their employees are an asset, not a drain, we, the consumers, the very people that keep a business in business, are stuck with poor service, employees that are, at best. Lethargic about going that extra step to insure customer satisfaction and continued success of the company.
Since most folks focus on the fast food industry as being the minimum wage leader, ask yourself if you'd harp over a failure in the minimum wage increase to the person taking your order? Remember, they're the ones that interact with the kitchen help.
Lastly, you have to consider that should the $15 minimum wage be passed, it won't go into effect immediately. First, it's usually spread over a period of 3 years. Second, it usually goes into effect on January first, to allow businesses to plan on how they will meet the increase. The absolute earliest it would go into effect would be in 2018, and it wouldn't jump to $15.
