The year is 2035 In many occupations, robots are replacing humans

Assuming the other determinants of demand for the two services are roughly similar, you would expect the demand for human ski instructors to be less elastic than the demand for human house cleaners. This is because skiing is a leisure activity so the demand is usually less elastic than the demand of a necessity like house cleaning. The lower the the price elasticity of a product, the lower the elasticity of demand for labor. The price elasticity of demand determines whether charge higher prices to consumers because of higher labor costs. If price elasticity of demand is inelastic they can pass the labor costs on to consumers so the elasticity of labor would be inelastic too.
