The rentseekers use their money to pay for favours in congress. The problem is not the market but the market in deception and destruction, which is not a market, but rather a mutual aid network for psychopaths.

One really simple solution that I see is this: your vote is multiplied by your proportion of taxes paid out of the total. Just like how your vote is indexed against your SP versus the SP of the rest of the system. The middle class is being raped by taxes, but their vote means the same result as the masses of uneducated, welfare trapped individuals, and the wealthy who got there by buying laws to vanquish their competition also don't pay as much tax for how much they get back.

The yield on lobbying for laws to shut down competition have several hundreds maybe thousand percent ROI. And these scumbags run the media who get the larger mass of poor people's votes under their control which more than accounts for what extra tax they are paying. When compared not just total sum of taxes but also the income remaining after it is levied, the super wealthy cronies power is massively amplified.

The problem is the structure of consensus building in the governments. This one potential solution would massively change the situation... but good luck getting anyone to adopt it who has a say. This is why we have Steem here, as a demo version of what it would look like, and, probably, it's going to grow up pretty fast and have a remarkable economic power as a collective, compared to its size (because it favours the meritorious in the redistribution).
