Thinking smart is a part of working hard. When we say work, we mean something that provides value, not something that requires a lot of physical effort.

I can "work" very hard pushing stones uphill like Sisyphus, and I probably won't get rich as a result.

A major reason why inequality exists is because the work ethic required for long-term thinking and planning is a model of behavior which children acquire from their parents through learning, observation, and imitation. Children from families where parents do not consider long-term goals worthy of pursuit are hugely disadvantaged.
