There's a huge difference between an accurate descriptive explanation of why someone is in poverty, and what mindset one ought to have if they are in poverty so as to maximize their chances of escaping it (or at least, of enduring it). The former should not inform the latter.
I am skeptical that putting the locus of control outside of oneself - even if partly or largely true as a description of reality - is a good solution to the latter objective due to the learned helplessness and depression that may be magnified by doing that.
