Who still needs a Gucci bag?

It's not just designer clothing that's experiencing a drop in sales, but also handbags and accessories. Brands like Gucci and Michael Kors have been selling handbags at deeper discounts because millennials have lost interest in their products.

It's also true that young people don't have as much money to spend on them. This is the "kiss of death for fashion brands, particularly those positioned at the top of the youth consumer segments," wrote fashion industry expert Robin Lewis on his blog.

Who cooks at home?

"On a certain scale, the ubiquity of food delivery services could potentially mean the end of cooking at home," states the UBS report. We are already almost in the era where people hardly ever prepare anything to eat at home.

The UBS report also indicated that, by 2030, online food delivery services will account for 10% of the food service market. If you haven't learned to cook yet, don't worry, because it's practically outdated. You're not going to impress anyone by cooking a filet mignon.
