Drastic? Well, then: kill NIMBYism. Just off with its head. We know the 18th century in England as the "Gin Craze", future generations will look at our period as the "NIMBY Craze".
Large-scale construction is absolutely possible. There were periods of massive construction booms all around the globe, especially after wars (when a lot of housing had to be rebuilt immediately). You can absolutely build a lot of comfortable middle-class housing in a fairly short time. Most German cities were rubble in 1945 and fine again in 1960.
But you need density and straightforward approval processes. No artificial scarcity caused by one-family home zoning and endless environmental reviews that are abused to stall developments for decades.
