> There's no such thing as a "living wage". It's a political talking point and you can set the line wherever you want.
This doesn't mean it doesn't exist -- it's just a social construct, and a useful one depending on where your priorities lie. The salient point is that some societies value this concept and draw the line somewhere. If you believe governmental regulation exists to protect the people (at least a little bit), putting a lower bound on what companies are allowed to pay employees in your country/governed region is important.
> Higher min. wage increases costs and disproportionately affects smaller companies, leading to closures in every region, country, state and city where it happens. This is also why giant corporations like Walmart even support it since it clears out small local store competition.
this is basically the same point rehashed -- I can't say that I added too many facts, but simply implying that min. wage increases hurt small business without discussing the increase in goods purchased is a shallow assessment. When workers who are likely to spend money receive more money in terms of wages, they spend these wages -- this should mean smaller companies will see higher sales as well as big companies.
And again, what the economy is doing aside, if you cannot afford to pay a wage that enables your employees to comfortably live, you likely should not exist, find another business. Businesses that attempt to operate in this space are externalizing their costs to society at large -- people who work at these companies depend on social programs that are paid for the society at large.
