Wouldn't it be better for a worker to be employed at, let's say, $10 per hour than to be unemployed at $20 per hour?
When California's $20 per hour minimum wage law goes into effect, two major things will occur. Number one, many businesses who hire entry level employees, will have to raise their prices to meet the higher costs of doing business, with the result of possibly losing customers, and eating into their business income. In addition, many people who worked at those companies, mainly teenagers and senior citizens, will be laid off or their hours will be cut back. Secondly, many small companies or stores will go out of business since they'll be unable to make a profit as a result of those extra operating costs of doing business.
To answer the proponents of the government mandating higher minimum wages, I'd ask this question, wouldn't it be better for a worker to be employed at, let's say, $10 per hour than to be unemployed at $20 per hour? Let the free market prevail in letting employers set their own wage rates as they see fit, and are able to encourage workers to join their company or store. If they can't find workers at the wage they offer, they'll have to raise them to attract employees, but that should be their decision, not the government’s decision.
