Since the old have done nothing to help the young (quite the opposite in fact) that will be an uphill struggle.
But old people did manage to produce a first-world country as successful as any other, get their language spoken all over the globe, vastly increase college education (which they thought was doing the young a favour), build a tech sector that pays wages considered ridiculous everywhere else on the planet, create the internet and basically give it away for free, give birth to and raise us, have much less racism and sexism than there were a few generations ago (although they both remain very real problems), avoid any wars that couldn't be fought with an all-volunteer military, and avoid destroying the world with nuclear weapons - something that seemed as inevitable, in its day, as global warming is today.
Thinking the old have done _nothing_ betrays something of an ignorance of history IMHO.
West in world context is not just the USA.
It's true that (e.g.) France hasn't reaped the benefits of getting their language spoken all over the globe, but they certainly have increased college education, the internet, and no major wars. And they also managed to introduce other benefits, like quality healthcare for all.
Below them are a much much bigger block of 60+ old people. They dedicated their lives to the opposite: narrowing educational access,destroying the generous labour market they inherited, stopping people accessing housing, some are even trying to reintroduce Nazi-ism.
I suppose all those babies paid for their own housing, food, education, healthcare and vacations for up to 25 years before they were productive members of society?
Not all debt is bad but our government is using it poorly. A 30 year bond on a bridge with 60 year lifespan is good debt. A 30 year bond on 2 expensive, 20 year wars with no positive objective is bad debt.
Said argument reminds of Monty Python's "What have the Romans ever done for us".
"I'll start respecting the elderly when they stop bothering me with their email problems."
That said, the horrible housing market is in my opinion mostly due to foreign mafia/dictator/oligarch investment through shell companies. The most expensive areas in London are all sold, but empty...
True, but this was allowed to happen by the current and old generation of voters.
Personally I think the correct line here is personal responsibility and fairness. OAPs have have had huge opportunitied. Until we've given the same to everyone else, they can wait.
