The French explicitly tried to ruin the country because it crushed their dreams on the North American continent.
Many of its West African colonies are used either as footstools, or treated spitefully, as though they had a bad breakup.
France really is a curse on most of its subjects.
Though, English colonies only noticeably improve AFTER decolonization. They get a few seedling institutions for their elites and an economic niche, but most importantly, the UK just doesn't extensively meddle in their day-to-day operations (beyond what's typical for their interactions with 3rd-worlders, at least).
