Want to reduce the cost of a wedding? Walk through shules and ask strangers to pay for it??
I cannot imagine anyone walking from shul to shul begging for money to pay for his son’s/daughter’s chassanah. Perhaps some yidden have no pride and would rather degrade themselves than consider telling their kids to get by with a simple seudas mitzvah after kiddushin or defer the wedding until they can afford to help pay expensive big simcha they aspire to.
