Chief amongst those, of course, in my view, is the climate crisis, a sort of meta-crisis that acts as a threat multiplier across so many other domains, but we still have a housing crisis—this Government has made some good progress so far, but we are just getting started, and that is obviously going to take quite some time for us to resolve. There is the crisis of the pipes under our feet that transport our potable water and our storm water and so on, and those are making us sick in many parts of the country. There is the crisis of deepening and persistent poverty around the country. There is the fact that, for many decades, our transport infrastructure has been neglected. Now, all of these are multibillion-dollar challenges that will need to be paid for at some point, preferably sooner rather than later given that we're talking about at least a three-decade infrastructure deficit that needs to get handled. So my argument here is that not only do we have an opportunity but a responsibility to put every dollar we can of that stimulus to work dealing with the long-term challenges facing our country. Because, if we don't, our children and our grandchildren will have to pay twice—once to cover the bill that we're running up for the current crisis, and again to get themselves through the crises that are facing them in their time.
