POLITICS

Frankly, I don´t believe in politics. I don´t believe in politicians. I really think that the Spanish politics had been blamed of are to blame for this difficult situation. While the government and opposition fight to be right, the citizens lost lose their jobs ("fight" is in the present tense and this clause needs to be in the present too). The situation won´t improve unless they (you need to say who you mean - government, politicians or citizens? - I presume you mean the politicians) agree to find a solution soon.
At the present, I´m very angry with the government there is in Spain (it sounds more natural to say "the Spanish government", or "our government") . Nevertheless However, I was too also very angry with the government there was in Spain before (better to say "the previous government"). I don´t know a government yet which thinks about person´s needs in the first time instance.
To be perfectly honest, I think that there are plenty the politician (I think you probably mean, "I think there are too many politicians") and they earn more money than they deserve.

Well done Elena! I have made a number of suggestions to improve the fluency but what you say is quite understandable.
