Found what I was looking for!
Lower Class - Benefits, council housing, no further education past secondary/GNVQ level. Little to no future planning. Even if higher income than working poor, it's all spent. Accumulation of stuff important.
[higher end of lower class would be similar but working very menial jobs like dinner ladies, maintenance, semi reliant on state but work too etc.]
Lower Middle Class - Working, but not in professions. Admin, Educational Assistants, basic jobs in bank like clerk, till etc. Some thought towards future. Goal to own own home. Set out to achieve certain things like Disney holiday, home ownership, new furniture. Paid for by self not the state. Not lots of extra money left but values having a bit set aside. Dc may or may not go to Uni.
Middle Class - University educated. Professions not jobs. Value pensions, long term saving, moving up property ladder is a goal. Most likely to go abroad on yearly holiday and have cultural city breaks with dc to Paris, Rome etc. Will move up until they get a detached house or semi if in expensive area. expectation dc will attend Uni. Have investments. Have to both work to maintain this. Will substantially contribute to dc university fees.
Upper Middle Class - more likely to have one higher income earner. Will have detached home and often rental or holiday let. More than a yearly holiday abroad. Ski trips. Pensions. Investments. Sizable inheritances. Most likely children are in private schools tho some won't start until high school. Usually have home help - cleaning, ironing, childcare via au pair or nanny even if one parent is home. Children will have Uni all paid for and family/friends who can get them into door of large companies. Parents jobs may be things like Consultants, Dentists.
Upper Class - Old money typically. Children not in state schooling but more elite schools where dc are registered from birth/early age. Usually parents work in private sector or reach height of professional (Dr who becomes CEO etc.). Trust funds. Could give all the money earning up and survive through old age but usually choose not to. Staff. These are the types of kids the royal dc will socialize with and find at their schools and through friends of parents.
