Yes, yes it is. I know there's a few conversions between countries to take into account etc, but it is a lot.
I'll give a few examples here,
1) Long story short, my parents went through a disaster none of it their own fault, and we had to evac our house for H&S. At the same point the place both of them worked (one as head manager, one as head chef) closed down because the owners wanted to retire.
We went from a comfortable wage which covered everything we needed including nice holidays (e.g. 3 weeks all inclusive hotel in the Caribbean 5 star) every year to the cheapest rental accommodations we could find, quite often living with other family members for free. In the space of 10 years we moved 15 times, our lowest was living in a caravan. Yes this is all relevant.
We ended up living where we own now, but to afford it a normal paying job wasn't enough. So while renting my folks set up their own company for preservatives, my old man also did private specialist catering contracts solo. At the point they made enough to climb out of debt (only a few thousand) made the rent payments, bills etc. My parents combined income was 3k. 3000 pounds to cloth, feed themselves their 10-14 year old son (yes this was a running trend for 4 or so years). Not to mention christmas, birthdays and the likes.
B) My partner has done 7 years in higher education, going through undergraduate, masters and PhD, she specializes in crop genetics. just as a FYI, she got a 1st in the UG and Distinction in Masters. When she spoke to this company during her masters they said if she completed it and got a phd, they'd be able to offer a stater job with 50k just get back in touch with them. She did a few weeks ago and they offered a starting pay of 21k and no annual increase for 5 years atleast as its only a tech postion. (same as she was offered previously). Instead, shes going into teaching now which starts off at 18, and a increase each year of 1. However her old school is desperate for over qualified teachers (its a 'posh' one) and if she completes the traning, starting with them is 27.
C) I myself, was looking at coming out of uni and apply for each zoo going hoping to get in on some research, but the starting pay is literally 16k a year and will hit 40k when you get to head keeper, estimated 20-30 years down the line. I'm now doing my masters and getting on to a phd involving mainly parasites and some herpetology stuff, but the job start point I get is 30k.
I know countless other people who are all in the same boat barley anything to start with and little progression.
Anyways as for taxing the rich extra? No not at all, its hard money well earned (most of the time). But I do agree a % tax is the best system.
