The Ninth Commandment has more to do with not bringing false accusations in a court of law. Thus you could also say that it has to do with issues of justice, especially as it relates to how judges and civic and political leaders treat those under their authority.
The Tenth Commandment has to do with coveting, which could, in principle, be related to being against egalitarian policy issues driven by class warfare and greed, which covets the wealth of others and which attempts to legally force equality amongst the masses of people, a la Marxism. When we force equality, we bring economic bondage and, in extreme cases, even mass starvation as shown in the communist nations of the last century. But when we create equal opportunity, then we promote liberty and freedom.
The Christian left believe in a zero-sum game in which there are only so many pieces of the pie available, so if someone—or if a nation—is rich, it is at the expense of the poor. But the reality is this: If Bill Gates lost his wealth, it would not benefit the poor in this nation or the world one bit. If the USA used less energy or had less wealth it would not free up any new resources for developing nations. Actually the real question should be “why are these nations perpetually poor?” instead of why the USA is rich.
Furthermore, wealth and resources do not originate with material goods, but with the creativity of individuals. For example, now—because of advances in agrarian technology—less than 2 percent of our nation’s citizens are presently farmers, as opposed to more than 50 percent who were farmers before 1860, yet we are producing more crops than ever because of technology. It is said that the state of California can literally provide enough food to feed the whole world!
Finally, if you want more resources regarding these topics, read my books Kingdom Revolution (especially my chapter on kingdom economics), and Kingdom Awakening (especially my chapter on kingdom politics).
