@IcyPlumShaker there are not enough billionaires in the UK to fund the public services, benefits and military.
The UKs economy has been in decline at the same time that services, benefits has increased. The Greens don't have a credible financial solution and in the recent by-election the open borders commitment was very popular.
The only way out of this is to get more people working and paying tax, perhaps they will need to reduce pensions but whatever government brings that in will be not voted in again. The UK can't afford the current setup, it was previously funded by oil revenues and money from nationalisation.
