    Yes. Perhaps an example will help: I live in Switzerland and make twenty times as much as someone in Moldova, yet I can buy only four times as many things. Now, am I twenty times as wealthy or four?

      This is from Google since I am working and can’t dedicate much time to this.

      Purchasing Power Parity (PPP) theory, in its absolute form, assumes the absence of trade barriers and transportation costs. Therefore, it doesn’t inherently account for them. In reality, trade barriers such as tariffs and other restrictions can hinder the applicability of PPP by preventing the equalization of prices across countries. This is because PPP is based on the Law of One Price, which suggests that identical goods should sell for the same price in different markets when expressed in a common currency, given the absence of such frictions.
