My DH is a higher - rate tax payer. He earns what he earns because he studied for years to gain knowledge and skills that make a lot of money for his employers. There are a very small number of people worldwide who have the same knowledge and skills. He could go and work abroad, and would if tax was put up even more than he already pays. He also pays thousands a month in maintenance, meaning his Ex and children are also not a 'burden' on the state.
Our cleaner is paid £18/hour. She enjoys her job, and happily admits she was not academic/didn't work at school. With the best will in the world, she is not particularly equipped to do a more challenging job. I actually think she gets a great wage for a job that anyone could do (although they might not enjoy it). Our gardener gets £15/hour for cutting grass/trimming hedges. Again, not skilled. I don't look down on them, they do a great job and get paid fairly. If we earned less, they wouldn't be working for us.
I studied for 5 years (degree + postgrad) to become a teacher. My hourly rate is £21. There are lots of teachers, so they don't have to pay more in order to attract them (although with the drop - out rate that may have to happen). I used to support my 2 children on this without help from the government as I worked full-time.
I used to have TAs who grudged me my higher wages, yet their standard of literacy/numeracy was in some cases appalling and they did not have many qualifications. They also did not have to work all the 'hidden' hours in the evenings and weekends.
My friend has spent the last 20 years working approx. 15 hours/week term-time only so she can get her housing benefit/tax credits/other benefits such as free vet treatment (PDSA), free eye/dental care etc. She doesn't see why she should work more hours, as she 'needs' her afternoons off to walk her dog/visit friends etc. and finds it 'too tiring' to work longer hours. I have had to bite my tongue on numerous occasions when she has said things like "It's alright for you with your wages" or been moaning about her pay.
Some people resent others their wages without wanting to do the extra study or put in the long hours necessary. I think everyone should get free healthcare/education, and the minimum wage should be higher/housing should be more affordable. I think people caring for family at home should also get paid more for the work they do, often with little/no support.
Do I think we should pay more tax? No, we pay huge amounts already. Do I think everyone should get similar wages? No, because then why would people even bother when they could do a job that they don't need to study for and that leaves their weekends/evenings free? Childcare needs to be more affordable/flexible, and people (like my perfectly - fit friend) need to be 'encouraged' to work for their money instead of working the system. Benefits should not be a lifestyle choice.
