In the south of the UK (the part where most of the jobs are) housing is a dominant cost in most people's lives. Since there's a shortage of housing and buildable land, the cost of housing goes up with people's ability to pay. This absolutely trends towards a zero sum game, so income distribution is a clear concern. Political power is also purchasable to some extent in virtually every country, so income inequality matters there too.
