We can't if we don't try

Here's Robert Reich's FB post, copied below, that challenges the Clinton campaign that we just can't do certain things and should grow up and accept it. Quote:

The naysayers are out in force: We shouldn’t even try for single-payer system, they say; we'll be lucky if we keep Republicans from repealing Obamacare.We shouldn’t try for a $15 minimum wage; the best we can do is $12.It's foolish to try to restore Glass-Steagall or bust up the big banks; we'll be lucky to stop Republicans from repealing Dodd-Frank.We shouldn't try for free public higher education; we'll be fortunate if Republicans allow any federal spending on education.We shouldn't try to reverse climate change; we just have to adjust to it.We shouldn't even try to get big money out of politics; we'll do well to slow down the inundation.We shouldn't be impractical, naïve, quixotic.
“Yes we can” has been replaced by “don’t even try.”



But it's impossible to achieve any meaningful reform in America if we don't try. And the only possible way to get there is to mobilize the public -- tapping into its energy, determination, and enthusiasm, mobilizing the young and idealistic and the older and determined.Besides, unless we try, we'll have to live with even more wealth and power at the top -- a rigged system that compounds itself by further concentrating wealth and power at the top, making future reform even more difficult.
This is the way we’ve always achieved major change in America: Not through "we shouldn't try," but through "yes we can."
