Sure I guess if you think you are in the group that won't be affected that is easy to say. If you wanted to be really crass you might say that since it has a much higher mortality rate among older people it will be a huge boon for government's fiscal position because it will cull the rolls of Social Security beneficiaries.
life is much more than just an economic contribution. Society is made by people that have relationships far beyond economics (family, friends..). Money plays a big part of course but people were also happy when there was less money around. Loosing one (or more) dear one is much more devastating that an economic crisis.
