Especially meat could be a great deal cheaper if these countries wanted to make that happen.
Food in the west is only cheap in one sense of the word, and even then if you compare how much of the cheapest bread today you can buy for the average monthly pay today versus how much of the cheapest bread in 2000 you could buy for the average monthly pay in 2000 it's almost a factor 2 less.
But yeah, that's still very cheap: nobody's going hungry at the increased prices.
Does that mean food prices have dropped enormously or could it be that families have to spend more money on eg. rent, gas, and health? Adjusting for inflation, the price of milk have only decreased 1.1%[1]

If we look at 1901, milk was around 6 cents per quart according to https://fraser.stlouisfed.org/title/bulletin-united-states-b.... Adjusted for inflation, that's about $2.29/quart today, or $9.16/gallon. That's over twice what I pay and over twice the average according to https://fred.stlouisfed.org/series/APU0000709112.
Housing is an area where supply is heavily restricted, partially because land cannot be manufactured, partly because of government regulations controlling what can be built and where. Surprise, housing is very expensive.
