The obvious solution is to run for office or become a journalist if you think it can be done better.
Also, in what way do you think the media has been bought off? I think the larger problem is that the media depends on advertisements for income which leads to sensationalism, but I don't see most journalists writing flattering stories in exchange for cash from the person they are writing about.
Because we have rigged the electoral system so that candidates have to spend enormous amounts of money to run a campaign, we have ensured that only the wealthy, or those who run on behalf of the wealthy, can stage a campaign. And there are plenty of journalists, already. The problem is that the news outlets they work for are not in business to collect and disseminate news, they are in the business to make money. The news is just a ploy to get eyes and ears on the advertising because it's by selling advertising that they make money. And over time, they have realized that phony news, and pandering op-eds on news events do that better than real news does. Also, big wealthy corporations know that if they spend enough money on advertising, the news outlets getting all that money will not be inclined to report things they don't want reported. So real journalists have no one to work for. Or they have to report only on the cheap, easy, sensational news that keeps those eyes and ears on the advertising and the corporate elite buying that ad-time.
Greed destroys everything it touches, and greed has totally infected our business, government, and news endeavors. They become more and more dysfunctional every year, and our whole society and culture suffers as a result.
There are moments when the people seem to still have influence. The complete destruction of Obamacare didn't happen because Republicans didn't want to face 10's of millions of voters who lost their health insurance because of their actions.
It's still happening as you write; as the republicans are gutting funding to medicaid and medicare and other social programs to try and cover the skyrocketing debt due to their tax cuts for their rich cronies. They have never stopped trying, and each time they try they gain more and more inroads.
We recently saw the reversal of policies dealing with families being separated at the US border. There are glimmers of hope here and there.
They smelled a unified reaction against it, and backed off (it was also a great smokescreen for gutting medicaid and medicare and social security, which may well have been it's only real purpose to begin with). The people have always had the power. But they have to act together to exercise it. Right now, the media is making it's money by constantly dividing us against each other. Outrage and righteous indignation sells ad-time. The politicians keep us divided against each other because it's the only way their horrible corrupt candidates can win elections. And the moneyed elites are keeping us divided against each other so we won't see what they're doing to us, and turn on them.
And all three are doing it together, very successfully. While we're still basically all blaming each other for everything, and thereby doing nothing to stop the people who really are doing it to us.
