Exactly. Assuming it doesn't go on care fees / any of our parents looking to piss all their money up the wall enjoying life (which we encourage them to do!), DH and I stand to inherit around GBP1m. Because of the way the different pots all work out, there will be very little if any inheritance tax paid on any of that.
We're very lucky and this is not something we are in any way counting on (and I try my best to tell my mother in particular to spend it on fast cars and holidays not horde it), but that's an insane advantage out of pure chance of birth. Of course I could independently decide to give it all to charity, but that's not human nature and of course I (with my own priorities) will use it for what I want to use it for. But the government should be working on levelling the playing field.
I am a high earning professional and so also work with other high earning professionals. The difference in actual wealth is amazing and it comes down to generational wealth. It's becoming more obvious actually as I get older because you see the clear differences in lifestyle for people you know are earning the same amount. It works both ways, I was often wondering how on earth some of my colleagues could afford the houses they had or the cars they drive until they happened to mention some family circumstance and I realize quite how much non-salary income they have. Then there are others who probably think the same about me.
The other big differentiating factor is how young you were when you met your partner (or if you never did / are divorced). There's a big difference depending on when people could afford to buy their first house, or what house they could buy then, which seems largely dependent on whether they were buying on one income or two.
