Look, I believe than in a lot of ways YES you can divide society (economically and politically) into two big ENORMOUS fields. Call it how you like, left and right, or republicans and democrats, I think you understand. The bottom line is that while somes win, others lose, the gain they make, they take it from the loser. Thats pretty much what Marx said, and we cant deny its influence in societies, in the past and nowadays too (where does the left come if not from Marx?)
Thats oposed interests, you can not have a win win situation.
In this country, the industry, the development of industry, it is and always have been, financed by the agro. That creates quality jobs, much more employment to everyone, mobility, progress, people to have they first house and salary with an obra social, vacaciones, etc. Do you think the agro want for them to the State take their money or to make them sell their cows in the internal market?
Its a zero sum game. You cant govern, I cant govern. Conclusion: the country dont advance.
So its impossible to not have this big huge, conflict present in Argentina. Thats the decadence, stagnation.
