In the last 11 months the US dollar has appreciated a by 24% against the Euro so the value of the dollar currently is far higher than it was in at the beginning of 2014 and perhaps its value can have a little more potential of appreciation over the coming months. The Federal Reserve is getting ready to raise interest rates next June. The economic crisis is not being has not been as huge big (or significant) in USA as in Europe (especially in some countries of Europe as all of us know) and the Euro currency became a lot weaker and probably will be even smaller more so until we strengthen our political and economical stability.

In my opinion, for Spain don’t to not have a stronger currency change might be more helpful due to this current economy economic climate. The unemployment rate is up of by 24%. The wages are becoming more and more lower and lower so with this unemployment rate in at its highest historical level and the salaries for workers in a continuous process of devaluation we don’t need to be academical economists to say than that the domestic demand has had better times.

In this context, actually the exported is exports are becoming a key factor in our growth and for me personally from this point of view I believe that a weaker currency can could be really interesting. If our products are cheaper we will sell more products of them abroad and if imported products are expensive perhaps it might be more profitable that if we manufacture our own goods. in this way our economic activity can start to improve. On the other hand the main economic activity in Spain is the tourism which contributed over 11% to the GDP and I think for the foreign foreigners it will be less costlier costly to visit us.

One of the main pillars of a sustainable economic growth is the political stability. An state honest and efficient state is the key for the development of our society and we all of us share this responsibility.

Very well thought out and written. My corrections are in red and my suggestions to sound more natural are in blue/grey.

Some notes:

(1) "the Euro currency became a lot weaker and probably will be even smaller more so".

In this context "smaller" implies that the actual size of the currency (notes and coins) would be less. The best word is "weaker", but as we had already used that word earlier in the sentence I used the term "more so" (= more weak).

(2) "If our products are cheaper we will sell more products of them"

To avoid repetition, I changed the second use of the word "products".

(3) "and we all of us share"

You can say either "and we all share" or "and all of us share".

(4) "The unemployment rate is up of 24%"

There are two possible corrections to this, depending on what you are trying to say.

If the actual rate of unemployment is 24% of the population, you would say

"The unemployment rate is up at 24%"

If the actual rate of unemployment is 24% higher than it was before, you would say

"The unemployment rate is up by 24%"
