At what point does the (UK) intergenerational economic gap become politically or economically untenable?

Apologies this more based around the current UK economy but this can also apply elsewhere.

Speaking as someone in their early 30s in the UK, things do seem to be increasingly bleak without much reprieve. Housing is becoming increasingly unaffordable for under-40s, triple-lock pensions are being vehemently protected, wealth is concentrated in older homeowners and younger workers are finding it increasingly difficult to find entry level roles, coupled with with a shrinking pool of job vacancies across the board. Wage growth has lagged asset growth now for years.

My question, is there a tipping point here, or does this just grind on indefinitely? Have we seen something happen in the past which is comparable to what's going on now? What would actually have to give? Politically, demographically, or economically?
