Pricing is almost yh same in US$ all over the world if you consider buying in relative bulk (60$/sack of rice of 100pounds = PREMIUM RICE. 35$/SACK is normal.
60-120 GRAMS PER DAY = 44 kg per YEAR = 1 sack of 35$ (or $60 if you feel fancy)
That leaves 363 days x 20$ to pay for beans, veggies, some protein and A TV, MOTORBIKE AND BRICKS & CEMENTS & REBAR.
If you give 20$/day to every FAMILY (not even person) in the world, all of them will have a DECENT CHANCE ON A DECENT LIVE including some luxury.
But we/YOU/ prefer to give them $2 a day but (y)ourselves 20$/hour and our overlords 20.000$/second.
YOU HAVE NO POINT NO PROOF NO EXPERIENCE NO ARGUMENT. JUST STOP REPLYING OR I’LL GO INTO MUCH MORE DETAIL
