Yet another notion that is currently being put forward as a "fact" rather than an "opinion". - that the Labour Party (and, by association , the left in general) is not the party of "aspiration".
Aspiration can mean a number of things. It may include getting a "high status" job, earning more money, buying a bigger house and private education, etc., etc. - and be largely self or family focused. It may also include maximising creative and practical talents, doing a job that is enjoyable and is felt to be useful, improving one's education and gaining qualifications, etc. I would think a lot of people aspire to some of these things, whatever their political leanings might be.
Some people's aspirations are limited by the circumstances in which they find themselves. People who have a physical illness or disability, or who have a chronic psychiatric disorder, or who have a learning disability/difficulty, or who have been brought up in care, in overcrowded and sub-standard housing or in poverty, etc. etc., are more likely to have fewer educational qualifications and be in low paid, precarious employment. Is this because they are not aspirational, or is it because they start from way back on the race track and are not given adequate hope and support to even aspire to, let alone achieve, particular goals.
Some prominent Labour figures are also jumping on the bandwagon, and it seems to me that they are the ones that are more focused on their own political advancement than on protecting everyone in this country, including those who, without support, will see many aspirations as unreachable.
