What do you wish that everybody knew?
Capital is not wealth. Dollar values can provide an approximate quantity of wealth when talking about a relatively small portion of the economy, because capital can be used to acquire material wealth within the context of a market economy. But the statement "The top 1% of the world own more wealth than the bottom 50%" is strictly false. Wealth scales logarithmically with capital, not linearly. Economics is better understood by looking at the underlying resources (labor, land, natural resources) and commodities (food, water, shelter, clothing, conveniences, transportation, entertainment).
