An income loan for younger people?

Comments on Tony Makin "Beware politics of envy when considering ways to equalise incomes", 19/06/2012, http://www.theaustralian.com.au/national-affairs/opinion/beware-politics-of-envy-when-considering-ways-to-equalise-incomes/story-e6frgd0x-1226399149922
Assume Makin's argument that income redistribution to younger people is inter-generational unfair, maybe there should be income loans that can be repaid in the future when their income exceeds a set level, similar to the HECS in nature, to younger people in need.
