Want2b, you are spouting drivel, for a start for someone who is working 100 hours weeks you seem to have a vast amount of time to be posting here. I know enough people working in the city and in law to tell you that 100 hour weeks are not common, unless you are counting every single breakfast and lunch meeting as "work" (and if so lucky you) and including answering emails and periods of time just thinking about it. Long hours are neccesary yes, but 100 hours is not common.
Do you know why its not common? Because the level of concentration you need to keep up in these jobs (in fact most jobs) is not possibe if you are that sleep deprived.
"If only those making snide comments actually knew what goes into getting to that type of position I think they might be a little bit more respectful."
The same could be said about those who earn less, many of these lesser paid jobs are extremely taxing and physically and mentally draining.
As for effort? It goes back to that where did you start from thing. I know plenty of bankers and lawyers, in my social circle ( yes even as a mere lazy and feckless teacher) I rub shoulders with MPs, high flying barristers, people who manage hedgefunds etc. Now isn't it funny that not all of them are the best, brightest and hardest working. There is plenty of nepotism still going on in the world, there are plenty of doors opened to you because of advantages and opportunities that people are given simply down to where and to whom they were born.
Check your privilige and stop whining about taxes.
