>pay for [...] research

Thanks for the laugh.

They might read research, but they aren't personally funding it.

You may wish to read up on the subject of government work, salaries, etc. before you go debating about it on the net. Most of this stuff is covered in early Civics classes, and as someone who presumably pays taxes, you might be interested in finding out where and how those dollars get distributed!
