Democratic control can provide equality and fairness, with every person one vote, rather than the market where some people having more impact than others, simply because they are richer.
Maybe because in America there hasn't been good governance for so long, trust is low, and the only solution many see is to simply chop down government to the minimum... but there are other solutions, actual democracy is one of them.

At the end of the day, their cure won't fix anything, but it will hurt a lot.
In general they're against people forming groups (corporations) to promote their ideas and believe that once you're in a group then you lose your right to free speech among other things.
