@sammsky1 I think you are putting up the wrong aspect of your argument as the aim for the criticism you are getting here. Nobody is having a go at you for not voting Labour, or even for considering voting Tory - They are criticising you for some very poorly thought out and over simplified criticisms you have made about people in society who are less fortunate than you. Several posters have openly said they'll be voting Tory out of self interest and nobody has said a word to them. The anger you have generated comes from a viewpoint which comes across as nasty and arrogant.
You have on multiple occasions said you educated yourself. You did not - your parents educated you when they paid for you and your siblings to attend a private school and receive a leg up that the vast majority of society do not receive. You've said it's irrelevant what your parents did for a living, or their circumstances when they moved to the UK but it isn't - It both proves the privileges you were afforded while growing up and (depending on the industry they worked in) could potentially be used to help you understand why helping others helps yourself.
You have also explicitly said you work extremely hard and everybody could enjoy the same wealth you do if they worked as hard. I'm sorry mate but you have 20,000 posts on a Man Utd forum and have been able to spend several hours distracting yourself with political and economical arguments on a Tuesday afternoon - you don't work harder than the nurse who earns less than a third of your salary or as mentioned earlier, the hospital porter who earns half as much again.
All of that aside, I have no doubts you work very hard and earn the lifestyle you enjoy. It's just that the opportunities and luck which has accompanied your hard work has allowed you reach a level which many never will.
There are a million reasons for being poor; from mental illness and depression to poor luck in a business venture. There's work place discrimination or even major life events like unplanned single parent pregnancies or the death of a parent at a young or critical age.
You've said that none of that is your concern but it is. We all benefit from a society which helps those who need helping. The idea that the best and brightest of us will magically be confined to those who have the wealthiest parents or the luckiest circumstances is silly and if you have a business which employs staff, you want a bigger, better range of candidates to recruit from. If you sell commodities to the public, you want more people with more disposable income to spend on those products. If you value living in safety and security, you want less people driven to crime out of despair.
