Him saying that is probably also a cudgel he uses to rhetorically discipline his workers for not raising their pay. Then when they don’t know how to respond he reads it as their reverence for him.

Even if it did, it’s just bragging he had so much wealth that being unemployed for 7 years made no difference to his quality of life.
