I agree, except that I don't believe anywhere close to 10% of programmers working in the UK earn that much on salary. You're probably a senior at certain big name employers probably in London or possibly working at a FAANG or similar if you're making that as an employee today. Contracting and freelance work has a much higher ceiling if you're experienced, well connected and working in a high-demand field, but obviously that income is not directly comparable to salary because you have the downtime, overheads and loss of employment benefits to consider as well.
