Task: Translation
Input (Spanish): Pero esta necesaria política realista y pragmática, que debería centrarse en la supresión de los obstáculos concretos identificados como factores indiscutibles de esta desigualdad, para nosotros debe fundarse en el concepto de complementariedad, el único que puede justificar una política voluntarista en la materia.
Output (English): This necessary realistic and pragmatic policy, however, which will have to be associated with the elimination of the practical obstacles identified as unquestionable factors in this inequality must, as far as we are concerned, necessarily be based on the idea of complementarity, which is the only one capable of justifying a proactive policy on the subject.
