Sure he earned a lot of money, but he was not exactly born poor. His father was very wealthy and Romney has not suffered financially a day in his life. That is not necessarily important, but I think it contributes to who he is.
Romney hasn’t taken his advantages for granted. He could have been a playboy and dilettante. Instead, he worked very hard and faithfully to be the very best husband, father, businessman, and person he can be. He’s like the proverbial servant entrusted with ten talents who brought forth ten talents more. He deserves praise for that, not ridicule and contempt.
