Answer:
Because France continued to be a large empire with many colonies around the world, despite having lost the colony of Haiti, which was one of the richest and most valuable.
Step-by-step explanation:
France used a mercantlist policy to benefit the country, and when the industrial revolution spread from England, it enjoyed very high and fast economic growth, which set the stage for its current standing in global affairs.
Haiti, on the other hand, was embroiled in internal wars, French embargoes, conflicts with neighboring countries, specially the Dominican Republic, internal political strife, natural resources depletion, natural catatrophes, and very high and unsustainable population growth. All these factors have contributed Haiti's poor level of development, high level of poverty, and low standing in world affairs.
