Am I right in thinking that he's suggesting lowering the minimum wage to $5/day?
That is exactly what it sounds like what he is saying.
If you are referring to the alleged trade bro, PhD, e67b, then you would be right. He would aim for less if he could.
No. Trade bro PhD e67b is not referring to e67b Trade bro, PhD. Trade bro PhD e67d is saying that it sounds like Sanders is actually suggesting that we need to drop the minimum wage to $5 an hour. Naturally I disagree with his comment because I have an economics PhD and know that comments like those are stupid.
Sanders would not agree to a $5 an hour minimum wage.
