Boomer mother-in-law demands son doesn't go out to eat so he can save for her retirement: 'Brian save your money, we have no 401k'

This family seems like they might need to clear some things up before their next dinner party. After marrying his wife, the Original Poster (OP) noticed his mother-in-law was always urging him to save his money. At first, he thought she was just looking out for him. It turns out that she actually plans to have her son-in-law fund her and her husband's retirement since they have no savings themselves. The entitled Boomer mother-in-law accidentally let this information slip when the family was all sitting down for dinner, and the OP suggested pizza, to which his mother-in-law replied, "No, Brian, save your money. We have no 401k; you need to save." This came as a big shock to the OP as he knows she only married her husband for his six-figure paycheck. Which, apparently, has not been saved at all. Not to mention the child support he owes from a previous marriage, so it looks like the OP is stuck. Well, the commenters on this post were not having it. Keep reading for the full story and the wild discussion that followed.
