Correct, but it's an unhelpful distraction from the more difficult structural problem. It's like having some hippie come along with a lecture about aligning your chakras and so on - there's a worthwhile spiritual philosophy underneath all the buzzwords, and a sincere intention to be helpful and motivating, but if you're not already in that meditative frame of mind then it's both unhelpful and annoying.

Talking about work ethic is valuable after other existential and economic anxieties have been alleviated and a person is in a position to make choices - not just select from expiring alternatives - about what sort of life style and goals they wish to pursue. Offered without regard to the situations that marginalized people find themselves in, it's mere pablum.
