This is only true if you consider financial savings the only type of savings. Preppers, for example, are very low-time-preference people who have chosen food storage, energy capture and storage, machines, tools, land, structures, raw materials, cabling, conduit, lumber, etc as their mode of savings. They will tend to do very, very well in high-inflation environments. This also ignores the fact that many assets owned by low-time-preference people (and/or the funds they hold) are leveraged, whether it be real estate leveraged by long-term mortgages, or 4% dividend-paying equities leveraged by 2% margin accounts. Inflation helps these people quite a bit.
