I’m in the minority here, but if the couple doesn’t have the education and means to support themselves they have no business getting married.
It is not the parents’ obligation to support adult children. They may choose to contribute, but this is a choice.
We paid all the wedding expenses for our daughters. They were married in our gardens and the meals were cooked and served here. No expensive hall, a couple of hundred guests seated in banquet tents for the seudah, cocktails and schmorg were around the swimming pool and basketball court.
Our sons married in NYC. We paid for orchestra, liquor, personal flowers and officiant.
We did not buy any of our children houses. Three started married lives in apartments we owned, paying the utilities and expenses. One moved into the MIL apartment of my Late MIL’s home and helped to care for her. As they had kids, they moved to the 3BR upstairs unit and MIL moved downstairs to the apartment.
All are professionals, many work in the CTL Law firm and all have bought their own homes over time. Our first tow married grandchildren are living in apartments we own as they finish graduate schools and get ready to earn a full living.
Would we buy a child a home? Only if there was some physical or mental impediment to their earning enough to buy and support a home.
What we would do and have done, is finance the home purchase so the children did not have to pay interest on a bank mortgage.
