Thatcher -- born in October 1925 in the small eastern England market town of Grantham -- came from amodestbackground, taking pride in being known as a grocer's daughter.
Jobs is the other example: he came from amodestbackground, overcame adversity, took huge personal risks when he put most of his net worth in to Pixar and NeXT, built a great company, and made a fortune, of course, but all the while he dressed in Levis and kept his personal life private.
