Hey Julieta,
So Argentina has changed a lot since you left. I doubt you'll find it as appealing as before. Society is divided, the economy is slowly but surely stagnating and crime and the black market are soaring. I would only come back if i could assure myself a dollar denominated income. The entrepreneur thing works if you have an e-business, you keep your US bank account and get people to deposit there directly. I'm sure there are loopholes, but you will have to be a different person to take full advantage of them.
I would like to know what Montauk_Project is doing, but i doubt it's for everyone.
I work in finance also and i must say it's a shrinking market. IT only makes sense if you are a recent grad or a managing director with contacts to exploit. There are slim opportunities in the middle. Most of the sector is moving to Chile and Brazil. To live comfortably you will need a net 20K a month plus salary if it's just you, and you will need a guaranteed 30% raise per year.
On a weekly basis you will need to cope with the following:
Blackouts (ever more and longer duration)
Strikes (increasing with inflation)
Worsening public transportation (es como estar en una lata de sardinas)
Razing costs (on taxis, buses, ABL, luz, gas, prepaga, etc.) once and sometimes twice a year.
Crime (more knife and firearm related robbery)
Anarchists (people who burn cars in the street)
Beggars (lots and everywhere)
Trapitos (pay between 5 – 100 pesos to park your car depending on where you go)
No FX market – you have to pay around 8 pesos for every dollar and rising (cuevas)
Less and less electronics at 100% mark up.
No foreign brands on white ware and no parts for maintenance
To get something fixed its 100 pesos to look 1200 to fix no matter what it is.
Cars are at least 120K pesos for a safe model with ABS and so on.
Going out is expensive (50 to 80 pesos a drink; 150-300 to eat out; concerts in the 800 plus range)
Travel is expensive 1500 pesos airplane tickets locally with delays etc.
And the looming uncertainty of a 2001 crash in the next 2 to 3 years
My advice is the following:
Wait till after the next presidential election (two years) and then decide.
Or find a finance job in Chile that is growing and many friends in finance are there enjoying life and their job with no worries. This is probably the best option. Get your LATAM connections in finance and monitor closely the situation here. Also you can visit more often and ski at Cerro Catedral with your son. Win-Win.
