Quite honestly was wondering about that statement myself. Don't know anyone <50 in Europe that "boils" their laundry, well except for the occasional "accident" or something.
As for powerful scented laundry products, wonder why the author of the article gave France a pass. Obviously he hasn't wandered down a laundry product section in that country, as he would have been bowled over by the perfumes.
Mostly such detergents break down along three main scents, Savon de Marseille, bouquet de Provence, and Lavender. To us the first most always smells of insect repellant (for some reason someone thought citronella would make a good scent for laundry), the same goes for the third. What one considers Bouquet de Provence scent varies, but IIRC Persil has a decent version.
Either due to many French homes line drying laundry (both in town and the country), it seems the detergents and fabric softeners are designed to last the duration, and that they do. Oddly one has never found "unscented" laundry products in France. We know several Americans who actually bring non-scented laundry products back to France when returning from a visit home.
