But why should the political class listen? They get the majority of their reelection funds from corporations and the rich. Their spouses and children are given good jobs by such donors, and if ordinary people do actually ever vote them out for not looking after their interests, well, as long as they went down doing what they were supposed to, they'll still be very well taken care of.
Get elected, do what your corporate masters tell you to, and you'll never ever have to worry about money ever again.
Only a sucker or an idealist would do anything else.
This is the fundamental problem with the US. There is no accountability for the political class. They and those who take care of them have made sure of it. Go to war with a nation which has never attacked the US based on a big lie propaganda campaign, or spy on millions of Americans, or torture, or deregulate the economy so that Wall Street can cash in and crash the economy, and hey, so what, there's no cost for you.
And as long as there is no cost for them, they'll keep doing it. Just like Wall Street, having been bailed out after crashing the world economy, will do it again. They got rich doing it, why wouldn't they do it again.
