Lew, the working people only have a vote, which political parties want, because they fought and suffered to obtain the vote.
Property (which includes wealth ) = Power and those with Property want to keep it and usually grow it; they would rather only people with Property had a vote.
Unfortunately people with Property probably run the UK (as they run the US ) but the charade of 'democracy' gives it legitimacy.
Political parties are largely part of the charade, and those with Property
have competing interests in gaining more individual Property and must strike a balance in giving those without Property certain titbits to inhibit that group from seizing that Property and also to use those without property to increase their own Property.
Have a listen to this guy. he will give a US version but the general idea is universal:
