There has never been a civilization in history where power and influence couldn't be bought.
That being said, It's not about figuring out some weird ratio of winners and losers. That's the wrong way of looking at it.
The key to making a more equitable economy (and society) is to focus on improving equality of opportunity.
Not equality of outcome, which you seem to think all left-leaning individuals want.
There reason why 1% of Americans own more than 50% of this nation's wealth is because they remove caps to their wealth-earning potential and limit economic opportunity for lower wage workers whenever possible. We do not have equality of opportunity in this country.
To base earning potential solely on "skill" or "effort" is to ignore the plain truth: many people don't earn more because they don't have the opportunity to earn more.
How do you define opportunity? Equity? Access to capital?
It's important to understand that cash isn't the most important thing when it comes to value creation. Earning potential is based on results.
A pizza place that makes shytty pizza gets shytty cashflow. On the flip side, someone who is about every aspect of the pizza experience is going to command raving fans and raving cashflow.
Too many people are looking for wealth in the wrong places. The top 1% don't "control wealth"... they have just amassed assets that make them essential to society because of their customer base as opposed to most people who simply will not survive without it (zero customers only employers)
Wealth is in the mind not in the pocket!
