The right just blaims the problems created by the rich on minorities like migrants, trans and homosexuals. That makes them look like they actually care about the people being hurt by the system, however also allows them to gain support from the rich. The rich do onw a lot of the media, which has massive influence on the vote.

The left party also knows this, so they usually do some minor things, which do not change the system too much in the hopes on not being hurt by the rich.

Oh and both parties are deeply corrupt.
