If the market value of labor has fallen below the threshold needed to live an acceptable (as judged by society) lifestyle, the burden of making up the difference should fall on society -- not arbitrarily on the companies which happen to do business in industries whose jobs require essentially no skills to perform.
Hypothetically speaking, if Google automated away 50M tedious and repetitive "white collar" jobs and those 50M workers are now competing for warehouse jobs, why must warehouse operators' pay a living wage while Google pays nothing for putting 50M workers out on the street?
The burden of caring for society's poor must fall on society. As it was society's technological innovation and policy decisions (i.e. globalization of labor markets) that has led to the destruction of unskilled labor's market value.
