12% of people are in poverty so 50% being low income sounds right. Especially cuz 60k a year is basically poverty in some parts of the country.

About 9% of kids are "food insecure" meaning their household income is so low access to food is uncertain or limited.

I wouldn't have technically qualified as either poverty-stricken or food insecure as a child, but I sure felt poor and went to bed hungry sometimes.

The numbers here may not be accurate, but the official numbers are bleak enough and certainly don't tell the whole story.

Not exactly, although the US numbers aren't good at all, especially not for a supposedly rich and developed country.

While approximately 13% (1 in 8) of children across the U.S. may experience food insecurity, estimated rates reach as high as 43% (1 in 2) in East Carroll Parish, Louisiana. Food insecurity is also more prevalent among children than it is among the total population in every state and in more than 8 out of 10 counties (2,593 out of 3,143).

62% of Americans living paycheck to paycheck amid inflation

Source. Not exactly about low income, but it shows that 62% of Americans doesn't have any savings.

However it is also inarguable that the numbers for Venezuela are much worse, and whataboutism is never a good argument anyway.

Those numbers line up pretty well with what I've seen in various news publications recently. What used to be the comfortable middle class is almost entirely gone. There is now a wide gap between the low-end rich and the poor who live paycheck to paycheck and sometimes don't quite make it. Wages have been artificially suppressed by employers and by our own government for several decades now, but costs have continued to rise.
