More than seven in 10 Coalition supporters think Australian incomes are fairly dealt out and fewer than half want people working weekends to earn more, suggesting the wealthiest are often oblivious to the struggles of the less-advantaged, an expert says.

An analysis of the YourVote survey of 143,000 Fairfax Media readers also found more women than men are concerned about income disparity, while professionals were more likely than labourers to believe income distribution is fair.

Despite the views of Coalition supporters, two-thirds of the broader population believed income was not fairly dispersed – which may explain why equity issues such as Medicare and access to the National Broadband Network have gained traction during the election campaign.
