"Working age people have less money because they have to subsidise the old, the dependent, the sick, and the wealthy."
The first three form the basis of our social contract. If you’re not happy with it other countries with little or no welfare state are available.

Your point ignores the generational contract that each generation strives to place the subsequent generation in a better position than they themselves started in. As per the Ancient Greek proverb: “A society grows great when old men plant trees in whose shade they shall never sit.”
The issue today is that the majority of Government spending is on a free NHS and public sector and state pension paid for by the current workers in taxation when those same benefits are highly unlikely to be available to them when they retire - for example the increases in state pension age.
Regarding the economy, Brexit which was more heavily supported by older rather than younger generations penalises those of working age through lower economic growth than those that are retired and on guaranteed pensions.
Similarly the Covid measures in order to protect the older generations most at risk caused an incredible amount of damage to predominantly the younger generation through loss of education, the economy and an increase in Government debt to £2.5 trillion which will be paid for by both the the youngest generations and those still to be born. All when statistically the younger you were the lower was the risk from Covid.
These are just a few examples and for a more detailed explanation I would strongly recommend that you read:
"The Pinch: How the Baby Boomers Took Their Children's Future - And Why They Should Give it Back by David Willets.
But it is for these reasons that the Boomer Generation is viewed as selfish by both younger generations and by future history.
