Usually, yes. But let's be honest, sometimes there is hypogamy as well. If you don't knot its definition, the term "hypogamy" refers to a person of higher social status who marries a man of a lower social status. The most notable case is Jenny von Westphalen who was born in an aristocratic family but married the poor philosopher Karl Marx (and then they were often poverty-stricken political refugees).
Nowadays there are still some hypogamy stories but usually the hypergamy wins.
There was a girl I loved nearly 11 years. After more than 10 years of fruitless love she became my ICQ-friend and even sent me some virtual love signs; one day when she wasn't sure she is pregnant or not, I was ready to go to her place (she resides in Germany) and to take care of her and her future child... it was a big love... but at the end, she got married to a richer son of a politician and businessman who works in East Europe. All my efforts -- improving my degrees (Master's at Philosophy, TEFL, 3 sports diplomas) /aka edumaxx/, improving my body (building muscles, learning more fighting techniques, entering new sports levels) /aka gymmaxx and/or looksmaxx/, improving my earnings (at least to the degree to own an apartment which already is a fact) /aka moneymaxx/ and improving my knowledge (psychology, anthropology, biology, history, foreign languages, sinology) /aka studymaxx/ were practically useless... but at least all these helped me to got some girlfriends and wives so far (not at the same time, of course). So, the self-improvement is useful, even when you can't succeed with your dreamful girl (aka one-it-is), there will be others that may like you. The hypergamy isn't something that should make you scared; the opposite, it should be a stimulus (a thing that rouses activity and energy in you), a useful challenge that will lead you to your point when you will ascend, dear good incels! Prove the incelophobes and the world that not every incel is a hopeless and/or dangerous person!
