It seems to me, that regularly increasing the minimum wage, in order to reflect cost of living, only results inevitably, in less opportunities for employees. Yes you get a bit more money, but employers are not going to be so generous with future wage rises, or even taking extra people on. Where we would have at one time, given a few opportunities to younger people, we are not doing so now, because the minimum wage is too high. What will of course happen, is that in some cases, employers will use foreign workers who work for less, therefore further restricting opportunities. I've seen this happen, especially in the building trade.
If you are a company that can afford this without impacting your bottom line, good for you. Most small to medium businesses are not in that situation, and they can't suddenly increase their turnover, profit margins or increase their prices accordingly. It's just not realistic. When you consider we're also paying in to work place pensions, higher corporation tax etc, where is the incentive for the employer?
If we were in a prosperous time of booming economy, that would be different but it's the opposite. There comes a time when you have to question if it's worth it.
