I don't think renters are falling behind? Paying rent is far less expensive than paying off a house; this allows people to save up
In my experience I have never see many renters saving money. Usually it's the opposite. Ofter renters would pay just as much as mortgage payments would be for a similar residence. With inflation after one or two years home owners are well ahead. Particularly those that don't insist on a McMansion as their first home. There are very few homeowners that think renting would have been a better proposition. Over the years it is mostly renters who tell me how lucky I am. You start getting lucky when you buy your first home.
