The problem is that to be hired someone (Jewish or otherwise) needs to be hire-able. That part of the equation seems to be left out of this conversation much of the time. If you want to earn more than $12 an hour you need to have a good work ethic and the skills that an employer needs.
A company hires people to create value for the company in some way. If you can’t do that they are not going to hire you, end of story. If the only value you can provide is doing menial work in a warehouse well then you are not going to get paid much because a lot of people can do that job. Jobs that pay well require specific skills.
Crying “Well people should hire more Jews” is pushing the buck to someone else. What have you done to make yourself a person who someone would want to hire? Start with that question and you might get some where.
