Are UK youth parliament correct that free bus travel for elderly may be cancelled and given to students instea?

Following rumours that the Conservatives if elected will scrub free buses for OAPs because country can't afford it, yesterday in the Youth Parliament in the House of Commons presided by Commons Speaker John Bercoe and witnessed by various MPs of all Parties and broadcasted on BBC Parliament Channel went further. Most of those who spoke argued that students can not afford the high fares on buses which they need to use to pursue their education and reduce cars off the roads and so reduce CO2 emissions so they should have free travel. Whereas some said most OAPs had plenty of money and owned cars and can well afford to pay the bus fares which students can not. Only two argued that elderly people are more in need because of what they have done for the country in past years and that young people have done nothing. One said giving youngsters free travel on buses will just make them "lazier and fatter than they already are". What do Yahoo community believe and is this likely to become an election issue in Britain to try to get more young people voting?.
