What a load of crock.
By & large "baby boomers" realise the horrendous error that was made when the UK joined an EEC and it turned into an EU. Younger folk are simply not old enough to have experienced any different and so don't know, so it is pure chance which side they support (except those who think subsidised foreign texting/calls/data, and the illusion of everything outside of the UK will be denied them if we leave and good reasons to support 'remain').
No generation thinks the previous one did well enough but they have to find out for themselves how little sway any individual has. Change is not easy, ans we can tell with the upcoming referendum. Everyone goes through realising that.
Few made any tidy sums on anything. It's simply lies. Everyone has to live somewhere, we all struggled and went without to buy a property: some today seem to think they should get whatever they desire immediately without any personal sacrifices. (I'm unsure why blatant delusions and claims would make you think. One may as well be persuaded to think that because someone claimed every "baby boomer" has £1,000,000 of gold ingots under their mattress.)
It has nothing to do with two fingers, but a lot to do with being fooled into thinking the grass is greener for everyone else.
Older folk are obliged to take a much more altruistic view since they will be here for a shorter period of time and need to ensure the right decision is made for future generations. Younger folk will know they are here for a while and are therefore more subject to being swayed by arguments that seem to advantage them now, regardless of how true that is.
For "baby boomers" what is best for us is what is best for our children and our children's children and so on. It's best for the nation in the medium and long term.
