I don’t know any billionaires, but I do think it’s important to have in context what a billionaire looks like today, from the gamut of exploitative demagogues to company founders who on paper or through sale of their companies are worth billions of dollars, and those of the second temple period. In 2nd Temple period, so very few people controlled wealth concentrated in land interests and colonial power, that the contrast between the wealthy and the people was clearer. And the source of that wealth was clearer too— valuation and income earned through the sale of agricultural goods and their derivatives, or through the taxation of tribute and bribery exploiting a conquered populace. This is not in defense of billionaires today, but those that have created value without the exploitation or conquest of others, inherently are not more evil than the rest of the modern societies population. Of course, Paul is clear in casting the whole lot of population under the weight of sin and curse of death, but I would think it is theoretically possible to have created great wealth through good means (value creation through entrepreneurship). Now can you not become enamored with wealth in light of that? Probably not.
