Big businesses are usually more efficient, even simply due to scale. They need fewer employees for the same amount of sales. Raising the minimum wage squeezes away the least-qualified employees, who are constrained in various ways (language, education, health, etc). The more qualified employees may and do of course benefit.
High minimum wages work well with a strong social security network, and higher taxes to support it. It's not what we have in the US though.
