1. The rich always have it better.
2. If you try to change rule no. 1, you just make things worse.
This type of pessimism is frustrating. And you are wrong.
Rewind about 500-1000 years. Pretty much 100% of the wealth around the world was held be a sovereign of some kind and his mates, who between them shuffled some tribute money around but otherwise gained more wealth by taxing the pittance earned by everyone else. Killing a random animal in a random bit of wilderness was a crime because all animals belonged to the King, etc.
A couple of hundred years ago this had shifted such that the state, independent of the crown, was stepping in, intercepting some of the wealth and redistributing it via social spending. Serfdom and slavery were on the way out. Meanwhile property and other laws had evolved so that the poor could start becoming the middle class through hard work, with obviously much less of a boost at the start than the landed gentry.
Today, at least in principle, we agree that the rich and privileged deserve no special treatment, and that at least the opportunity to acquire and hold wealth is akin to a universal right. The fact that we haven't fully implemented a system which puts this into practice doesn't mean that "the rich always have it better", nor does the fact that we have recently experienced some short term backsliding on the move from "the king has everything" to "everyone has something".
In other words, you need to use a larger data set than just the last few years or decades. On a longer timeline there has been a very successful reduction in the extent to which the rich get their own way. The current thrashing around by companies and wealthy individuals post-financial crisis indicates to me that they appreciate that their only chance to maintain their privilege is to manipulate things outside of the rules of the game (political influence and tax evasion, for example).
