"hard working people who go out come rain or shine and do their day's work"
This is most people. You do realise that, right?
Turning up to work and earning a low wage doesn't make you automatically some salt-of-the-Earth saint. It makes you the average person. And conversely, earning a high salary doesn't automatically make you a posho who never does a day's work.
Do you think companies give 70k a year to just anyone who turns up once a week? Or that it was all down to luck? Or that Mummy and Daddy must have helped them out? Because if you do, you haven't got a clue.
And Polo lessons? On 70k? Do me a lemon.
If you live in or around London 70k can get stretched bloody quickly when you take into account a mortgage, all the myriad costs of running even a shite car, gas and electricity bills on a 3 or 4 bed house, council tax which is the most expensive in the country, travel costs which are nearly £200 a month, water which is among the most expensive in the country, groceries, all the costs of having children, tv licence, internet, various loans and credit cards, buildings and contents insurance, life insurance, pension contributions and MAYBE if you have some left over some money into savings for University costs, and then most importantly some booze to unwind from an hour and a half commute.
If that list sounds familiar, it should because it's probably what we all have to deal with.
Now bear in mind spending expands with income and everyone "feels" the pinch because it's all relative. My last car cost 2k second hand, my current car cost £500 second hand and it's the biggest piece of crap you've ever seen and I haven't been able to afford to fill it more than half way up for months. Most people live paycheque to paycheque, so just because someone moans about having to cut back on spending on something you would consider a luxury doesn't make them bad people.
You're posting on a free internet (in terms of speech, not cost) in a free democratic country with free healthcare for all and a benign (well, mostly) government, under the protection of a civil and criminal legal system.
If you asked someone in Sudan or some godforsaken hole like that about living in a bubble I think they'd laugh at your question more than anything. It's all relative.
