My take is that fragrances in the 80s were termed "powerhouses" because of their extreme sillage and lasting power. This stems from the fact that fragrance houses (at that time) were trying to beat one another to come up with a great fragrance with no expenses spared with regard to using quality ingredients (that's why they smell so strong). It was a matter of establishing a brand name as well as for prestige reasons. Unfortunately, nowadays it is all about corporate profits and margins. Hence, we are left with non-descript chemical-smelling watered-down perfumes today (where cheap ingredients is key). It often makes me smile when i keep seeing people asking fragrance houses to resume production of a certain perfume. They would not for two reasons: To make the exact same perfume is difficult given how much more expensive the same ingredients will cost today (compared with 20 yrs ago), not to mention availability (eg. civet, ambergris..). Also, to even approach similar quality and sillage, and try to keep prices sane, it will only mean thinner profit margins. Companies are way better off making cheap perfumes and making them look expensive through packaging.
