This is not true, it’s confusing two different concepts

which is a special case of the Gorman form.
 
Indeed, the marshallianMarshallian demand function for the nonlinear good of consumers with quasilinear utilities does not depend on the income at all (in this quasilinear case, the demand for the linear good is linear in income):
::<math>x_i(p, m) = (-dv(p)/dm)/(v(p)/dp_i) = -1/(dv(p)/dp_i) = (v_i')^ {-1}(p)= v_i'(p)^{-1}</math>
Hence, the aggregate demand function for the nonlinear good also does not depend on income:
