Not every Argentine uses "malas palabras" all the time, it depends on culture and context. Also, when you use one word a lot, it stops being a curse and becomes a tagline and nobody thinks of it as an insult or imprecation. Our youngsters constantly use "boludo/a" when talking to each other, but there's no insult intended, even though the word is an insult and a "mala palabra". In the same line Chilean youths use "huevón" (pronounced and written as "weón") all the time, and Mexicans add "chinga" or "pinche" every two words.
We are having inflation in Argentina. It's now arround 30% per year. The reason for that is that consumption is growing but there's very little investment. The government is constantly pouring pesos in the market but also dollars as they get a lot of them mainly through the export tax on soybeans. That way, the room went from 86 pesos to 140 pesos (a 63% raise) and in the same time, the dollar went from 3,30 to 3,90 (only a 19% raise). We are having high inflation measured in dollars.
Brasil has a worse situation because the dollar value in that same period went down, so everything is very expensive now there.
