Left and right

Hello Rabbi Michi.
You often say that the current coalition is extreme left. I would love to know if there is a source where you elaborate on this matter. In general, an interesting question is what left and right really are, since these terms are so widely used today by everyone.
If there is no such source, I would be happy for you to briefly explain how you see the difference between a left-wing security and economic perspective versus such a right-wing perspective (and if there are other aspects to the matter, then those too) and why the current government is left-wing.
Thanks in advance.
