A large component of the dutch GDP as well as population is below sea level. They have been building dykes since centuries. Considering the large coastline of the US, there is definitely a huge cost to climate change induced sea level rises, so some poorer settlements will likely be given up but on the other end I doubt that e.g. downtown boston will be one of those settlements. It's more a question of how economical mitigation measures are vs resettlement. Overall the costs and damages will vastly outnumber the (massive) investments that we'd have to do now to slow down climate change.
