Which of the following was true regarding conventionally measured income inequality in the U$.$S$.$ during $1968$ to $2007?$

The income share of the top $1\%$ of income earners tripled over this period

The income share of the top $25\%$ of income earners remained below $60\%$ during $1968-2007$

There was a steady decline in the income share of the top $5\%$ of income earners during this period

According to Natural Law, ethics does not change over human nature, not human culture. In order for ethics to be different, human nature would have to be different. Progress in natural law thinking means discovering new aspects of the natural law$-$e$.$g$.,$ that laborers in capitalist countries have economic rights, as the Church argued in the late $19$th century. Progress does not mean that what was once right is now wrong, or vice versa, since that would be a contradiction.
