Why they do not trust us??

I came to the MCAA GA after a 2 days conference on research (also in Brussels) and thinking to the discussions that we had at that conference I would like to focus at the connections between us and the policy-makers. 

After the conference (really interesting, I would say) and after hearing the policy-makers, I honestly think that or they live in another World or they do not mind what problems we have. Anyway I have a topic that I think everybody should discuss and bring to the policy-makers through the MCAA: why we always must demonstrate that we are able to go successfully ahead with our research? Even though we publish in Science, Nature, all the most important journals, even though we get the Marie Curie, the ERC fundings ... we always must demonstrate the we are good otherwise no money and no job. Why they do not see the mobility/stability on the other way around trusting us, giving long term fundings to the good researchers and then evaluating our work on the way? Do they think that they can save money in this way??  They probably do not understand that short-term fundings are much more expensive than long-term because having 1-2 year positions we must always spend much of our time looking for a new job (wasting a lot of time), any time they open a new call it is a big cost for the community, and any time we change job/position/place we lose a lot of time and experience. The procedure is not effective at all. Please TRUST US! At least once we have demonstrated some skills ...
