Why is it so hard to find a lower-middle class woman to date?

It seems like every time I ask a woman out, she expects me to spoil her and if I don't want to buy her a boba tea and a sandwich for lunch she gets pissed and angry. I work hard, I work at a warehouse for 6 hours a day and do not have much money left over to spend on women. I just want to find a woman in a similar financial situation to be with... but it seems like they are hard to find out there.
