I agree with pretty much everything you say.
Unfortunately the VI in keeping the system the way it is is strong.
I was hoping under Labour we might get fundamental policy changes. To me the most dangerous example of imbalances is when you get one government in charge for a long time, but then when the other replaces it they double down with exactly the same policies.
So for example in housing (a bugbear of mine), Thatcher basically bought in the right to buy, fair enough at the time. But then during the 10 years that followed Tony Blair and Labour basically doubled down on this (Blair built fewer council houses in his entire tenure than the supposedly "anti council housing" Thatcher did in 1 year of hers). That's led to some of the issues we see in the rental sector, housing problems and housing affordability now.
Re Labour currently, they just seem like Tory lite with a few woke distraction policies tacked on to try to control the faithful. The imbalances are continuing and they are not doing anything about it. But in my opinion there is great opportunity through change, but it going to take great pain for some sections (middle class especially as those are the people with assets) to go through those changes. So takes a leader with guts and determination and a vision greater than the next 5 years. Not how our democracy is set up.
Definitely I see increasing inheritance tax and undoing the loopholes as just, I see it more as the older section of society paying for services they never properly paid for in the first place but funded through borrowing. I don't see the fairness in making the young pay for this. But again making this change seems very difficult, especially since huge numbers of people see inheritance tax as a negative even though they themselves will never pay it.
I agree totally with the unearned income issues. But again the VI there is strong, and the screaming is going to be incredible when the shifts finally start to happen.
Unfortunately most people don't spend enough time thinking about or voting on economic issues beyond what is important to them. This probably means we are going to end up having a deep collapse followed by radical changes followed by recovery rather than a managed transition to new policies that work.
