The working class should be really defined as people who are one paycheck away from defaulting on debts like the recent US shutdown showed.
Yes, that is also a characteristic... and add to that the inevitabilty that, because you hit already the ceiling of your wage/salary structure... the lower your skill-set, the faster....this is not going to improve... ever.
For these people the increase in real salary/wage compared to inflation, is the only perspective left.
And especially for the bit older people: They will be wary of the risk of losing their job, and also the risk of not getting a job back anymore at the same salary/wage level.
Being aware of that "being stuck"... that some things will never be for you... as escape available the lottery, the bookie.... your football club hero yes, perhaps your son...
but you no..... and accepting that financial reality is almost cruel.... many people push that away... hope dies as last.
And that is imo exactly one of the traditional values of the socialist movements: offering the hope against that "being stuck", with very practical and rather plain targets, and offering at the same time that reality awareness and politicise that in simple terms.
That's also where "education for everybody" comes in as traditional value. If not you yourself... then at least your kids should haver the chance.
For "workers": Simple terms. Not burdened by abstract ideologies, complex analysises or how you get it all consistent.
It's giving hope, direction, practical achievements, protection, in exchange for trust....... and hopefully solidarity from them when they do reach a high income group.
The problem with above is that, although as values still valid, it does no longer dominate the scene in the perception of most or at least too many people.
Left wing affinity, progressive values affinity... it is nowadays mostly coupled to a better education level.
The old "trust system" on a minimum and protected level of material benefits by the union/party is partially broken.
Many people do interpret the benefits that they have as their
own achievement, from their
own education, from their
own smart choices in job hopping, in their
own (little) career, up to seeing their employers as quite allright because, after all, that employer supplies, "takes care", of having that job available.
And even if you did manage to get a bit higher salary, you partner up and save together for that big step of buying a small home, your
own house, your
own place under the sun... but meanwhile fully in the debt trap.
And when housing prices go up, your own house no longer under water, you are happy... and that increasing housing prices is mostly coming from housing shortages for starters... well.. uh... uh.
Where are you now on the political stage ?... a mini capitalist house owner, living from paycheck to paycheck, making banks richer hoping that house prices further go up and...
are you still in favor of public housing projects from government money for affordable rents reducing house prices for owners ???
(is my personal pet: in urbanised areas at least 80% of all houses should be public state owned or state controlled for affordable rents.
Thatcher has caused a revolution indeed... also with her housing program.
