With gains in worker productivity, we should be able to support more people per worker than we previously did. The strain on the economy is a problem of failure to adapt economic policy, not intrinsic to population growth leveling out. Infinite population growth was never going to be sustainable. If you went back in time and told Malthus that in sufficiently prosperous societies people ended up having fewer children, he would have jumped for joy, as it's vastly preferable to society growing until all resources are depleted, then dying off in droves due to overpopulation.
