From a reader:

She writes:
Men and women who stick together, stay out of trouble, and work steadily are rarely poor, I wonder if the statement would be even stronger if she wrote “…and work
steadily rarely stay poor.” Not only would it make her point about morals
and behavior, it would also belie the “class warfare” pont that the rich
are always rich, the poor are always poor, and those people stay that way.
Poverty is mostly transitory and often a disease of the young. Those who
work hard and stay out of trouble are likely to spend less of their life in
poverty. Besides the obvious criminal avoidance, people who can make
discipline part of their lives are rather less likely, I’d imagine, to wind
up under a crushing debt burden.
