Gaga has ranked within the top five every year since her debut and the one year she's unable to tour and her album 'flops', she ranks #19 - still better than any other celebrity, primarily her contemporaries, that have ranked lower than her in previous year's. Gaga's also the third top-earning female musician of all time, earning over $317 million in five Forbes calendar years.
So, honestly, no one's "destroying" Lady Gaga but herself. She's still one of the most influential musicians in the world today.
