The european community will demand visas to bolivian citizen

Starting april 1st, the european community will begin to formally demand every bolivian citizen that enters this region to previously obtain a visa. According to official sources cited in the spanish newspaper El Pais, this measure was taken due to the “intense migratory pressure” from Bolivia. Other countries of the area already in the list of nations that need a visa include Colombia, Peru and Equator.
Despite the declarations made by spanish and european community’s authorities, it seems pretty obvious that in a short term other latin american countries will be added to the list. I hope I’m wrong, but I’m not usually optimistic in these issues. And even less, if we analyze how has the migratory policy and the US - Europe tourism regulation evolved, with increasingly more strict measures.
A couple of weeks ago, I had to go to a travel agency, and on the computers you could see a paper sign with the entry demands to the European community. A certain amount of money per day, credit cards, round trip tickets with no more than a 90 day stay in the region, etc. And I thought, while an european backpacker can travel almost anywhere in the world with a relatively small amount of money and have a long trip, most of us are not allowed to do that. Eventually, only thos with the right passport will be able to backpack around the world. Or am I being to pessimistic today? (Thanks, José, for the notice).
