I want o know how wages and prices of different goods vary relative to each other in various countries. For a country with high salaries, the cost of wages for waste collection will be a greater percent of the total cost for collection, compared with a country with lower wages.

For example, in one country, a waste collection worker might make an annual salary equivalent to 3 times the cost of a truck. Labor is more expensive here compared to goods.

In another country, a waste collection worker might make an annual salary equivalent to 2 times the cost of a truck. Labor here is cheaper compared to goods.

And the relative price of goods can vary.

For example, in a country with cheap fuel, the fuel used for a collection vehicle in a year might be 1/10 the cost of the vehicle itself.

In a country with expensive fuel (relative to the price of other goods), the fuel used for a collection vehicle in a year might be the cost of the vehicle itself. Thank you!
