We do not have tens of millions of hungry people unless you're including being a bit peckish before lunch time.

EDIT since I can't reply to irish-coffee for some reason: nobody said literally starving, OP said experiencing hunger or deprivation.
Pretty big gap between literal starving and food insecurity.
This is a miscategorization imo, food is incredibly cheap compared to any American income or welfare program.
You have to drill down to "very low food security" to reach the point where someone reports having reduced their food intake, which is a 5.4% number.
Still higher than I'd like! But it's not 47 million people.
