The links to the articles in your post says plenty about the practical reasons why a more livable minimum wage won't cause harm. There is economic theory that supports this observation and shows that this extends beyond Seattle's small restaurants.. I posted the following on another thread but since the right repeats itself I don't know why I can't as well.
The myth that a modest increase in the minimum wage will cause an economic storm for the poor comes up again and again. First of all, a minimum wage is just that, a minimum that is set by a govt entity. Nobody can work below this, so nobody can price minimum wage workers out of their job except for multinational companies working outside the country. This too is under the control of govt. We've allowed this to happen. We don't have to.
Another myth is that minimum wage causes unemployment. Not true. I'm giving the link below because I'm going to quote from it.

The conservative right as always use simple arguments. In this case they use a simple model taught in first year economics classes to make their argument, which is:
- the labor market is perfectly competitive,
- the minimum wage covers all workers, and
- worker productivity is unaffected by the wage rate.
Under these assumptions, the effect of the minimum wage is quite straightforward: the introduction of a minimum wage results in unemployment in those labor markets in which the equilibrium wage rate is below the minimum wage.
A better model looks at the benefit of employee retention, which includes efficiency due to experience, cost of hiring and training, benefit of employee loyalty. There are a number of theoretical models that use these concepts.. Among these are:
- monopsony models, and
- efficiency wage models.
Using reasonable factors that affect workforce efficiency, these models show that small to moderate increases in the minimum wage will have no adverse effects on unemployment (and may even lead to reduced unemployment).
A more detailed look at these studies are contained in the link (see above). The myth of increased unemployment due to a minimum wage is based upon an oversimplified look at the situation. A slightly more complex way of using reasonable factors that businesses know to be true results in positive results with the minimum wage..
