No, we can stand up to the large corporations. While it might seem that one person would not have a chance going against a large and powerful corporation, there are ways to counter their power and it is vital that we all stand up to protect our rights and the rights of those without money or influence. Today, with the power of the Internet, there are more ways than ever for people to raise awareness of corporate wrongdoing and to reach out to millions of people. In doing so, even one person can attract a lot of attention and find many supporters to band together, attract media notice, boycott products of unresponsive companies, and create a groundswell to help bring about positive change.
Corporations are run by money and money is power. Money also runs the country. So it is very hard to stick up against this but it needs to be done to be progressive and keep some our rights. This does not mean that there will not be sacrifices, though. In order for change to happen that is usually the case.
Corporations are powerful, and are probably even more powerful than our governments at certain levels. Many of them may think they can get away with what ever they want. Many of them probably do already get away with anything they want. Eventually it will catch up to them though. All they have to do is start to upset to many people, and people will up rise against them. Just like people have always done since the beginning of time. We have already had a bit of a taste, but apparently not enough people are that upset yet.
