Electronics and factory farm tomatoes are cheap, and near nobody lacks food or a phone.
Good teachers, black caviar, decent real estate away from poor people (lol) are inherently scarce. As for social economics enquiries, they always seem to require people to give up fruits of their labour for no compensation. As much as I like free stuff, I very much find this undersirable.
The price of tomatoes has inflated at a rate of about 3.55% per year, up a total of 1,049% since 1953. In that same period, minimum wage rose from $0.75 to $7.25. In 1953, an hour's work would have bought you one tomato with a bit left over, today an hour's work leaves you short. Tomatoes have not become cheaper.

Or don't bother with canned tomatoes from your link - things like flour, butter, milk and meat all got cheaper relative to the minimum wage.
Fresh tomatoes went from 25-30 cents per pound to 1-2 dollars per pound, i.e. got cheaper too.
