It's probably as unlikely that you would nowadays become as rich and famous as Bill Gates, as it was unlikely in the 17th century that you would accede to the ranks of the French aristocracy.
Скорее всего, сегодня так же трудно стать таким же богатым и известным как Билл Гейтс, так же как в и 17-м веке было практически нереально стать членом французской аристократии.
