The issue these comments have is their disconnect with reality. It's a simple math that most can't and will never be a millionaire, no matter how hard they work.
Does hardwork and intelligence and investment factor greatly into success? Of course! But you know what else factors greatly into success? Something people like her will never want to admit because it makes her wealth that much less impressive: luck.
There are only so many high paying jobs available. There are only so many products people are willing or able to buy. Even if EVERYONE works REALLY hard and does everything they are supposed to do, they will not all get six figure jobs. They will not all be able to become millionaires. The moment I read her comment I thought to myself "She sounds like someone who never actually had to work for her wealth". Low and behold a few sentences later...
There is nothing wrong with being rich, or inheriting money, and there are still plenty of genuine rags to riches stories of people obtaining great wealth through hardwork. I was born into a multimillion dollar family. My grandpa on my father's side became a millionaire under a 92% tax rate through hard work and accumulating the wealth he needed to buy a factory. He was smart, inventing a kind of egg peeler and a three sided cookie sheet. He was also lucky enough to have opened his factory at the dawn of WW2. With the start of the war he repurposed his factory and made much of his fortune on military contracts. With that money he continued to grow and manage his wealth throughout his life and now, 70 years later I have far more money then someone my age has any right to have, but gosh darn it I am using it to pursue personal projects and give myself a chance to pursue a career I love rather then a career I need. That being said, it's important to understand where your wealth comes from, and not allow it to give you a warped world view. I'm friends with enough "hard working penniless college graduates" to know that hard work does not equate monetary success. It only helps you get there.
My grandpa on my mother's side worked incredibly hard himself. He held numerous jobs, ranging from waiting tables to owning his own fish store in South Florida, and was incredibly active in his community throughout his life. Yet at the end of his life he lived in an apartment in an increasingly run down condo complex, while my other grandpa lived in a million dollar bayside home in Miami Beach.
