What does the phrase let them eat cake mean?

The phrase "let them eat cake" is often attributed to Marie Antoinette, although there is no solid evidence she actually said it. It is commonly interpreted as a callous remark suggesting that if the poor could not afford bread, they could simply eat cake instead, highlighting the disconnect between the ruling class and the struggles of the common people. This phrase symbolizes indifference to the plight of the impoverished and is often used to critique elitism.
