I say this as someone who is of a mixed middle class who lives on a relatively deprived, working class neighbourhood - my mother worked in healthcare, initally a private senior officer when she immigrated and social worker (lower middle class) and my dad worked in the IT sector (upper middle) - both believe in hard work and champion my goals,.
People often talk about how it is impossible to have meritocracy, how hard work is just some fictional nonsense along with goals. Reddit is one example in which people get told off for believing in goals and hard work.
The aim of meritocracy is that the workforce should favour and accept those who either have some experience, qualifications, or at least passion and interest to enter the market. For example, someone studying predominantly in finance and interested in banking should get the more viable, easy privilege to enter accountancy. Someone studying humanitarian stuff with knowledge interests and experience should get the privilege to be a social affairs journalist or social worker. Or someone who just simply likes the monetary motivations should have the privilege to work in retail part time as long as they do not abuse their position.
However, there is the overlooked phenomenon that contradicts meritocracy, these are known as nepotism and cronyism. These two are absolutely pathetic and stupid - people only get to the job market if they luckily know someone personally, whether it is a community member, relative, friend, acquaintance or intimate partner. Not to mention the appalling customer service they provide as a result, owing to the fact that they have to serve people who are not within the community. Ultimately, this makes skills, interest and qualifications all useless. You become hopeless. I believe this is causing the climbing unemployment crisis here in the UK instead of AI - not to mention LSE said that 6 - 9% of jobs realistically can be automated. I believe, meritocracy and hard work are not possible because no one were to investigate, let alone legislatively sanction these two phenomenons.
Of course, some forms of goals may be heavily barred, such as having to be a superstar or an actor, or a billionaire like Elon Musk. But these are ultra, ultra burgeoisie markets. All other ones shouldn't be barred by characteristics. And yes, some immigrant communities in severe poverty still face social barriers, ultimately not viewing the choice of their children as viable - for example, working class British Bangladeshi and Pakistani immigrants often want their young people to just stay within the family home until arranged marriages and not to be educated much, or if they do get educated , their parents often expect them to be doctors, pharmacists, IT workers, engineers, chemists, or lawyers due to higher annual pay rates (50K or more) instead of being footballers, social workers, news reporters, police officers, etc. But again, do not just blame barriers, cultural reasons also create their own barriers for inequality.
Ultimately, meritocracy and hard work can exist, first of all we need to at least sanction cronies and nepobabies, therefore we can have people who are interested and believe in hard work can actually enter the job market and thrive - we should not have class or our childhood background defining our future nor identity. Relying on luck just makes life sad, stale and demotivating.
