And I support this too. The youth of today don't have it harder, they have more opportunity than any generation before them. Now that may create different challenges, but it's not harder. I spend time working within my old school to help students prepare for working life so I have a very clear understanding of what the reality of being a child today is compared to what it was in my day and trust me, there is much more going for them today, but a different mindset that is frustrating. To my point up top, no child of today can possibly understand that however as they only have their experience.
I wouldn't agree that this generation has more opportunities than any before them. Different opportunities sure, but more? Probably not. Just as this generation don't have it easier than previous generations, but probably don't have it harder either. The struggles, opportunities and hardships are different.
For example todays generation are finding it harder to get on the housing ladder and are predicted to be poorer than the previous generation, but at the same time that is evened out by greater accessibility for self growth, communication and a wide variety of other things that have changed since the last generation were young. That in itself brings challenges and difficulties that previous generations have not faced.
You may think you know what is going through the minds of the current generation having helped in schools, but do you really? Just as the younger generation can think they have an idea about what it's like to be old - but we don't.
The whole "we had it much harder in our day, your generation don't know how easy it is" has probably been around since the 'invention' of generations...
As for the original question. It probably depends. Personally I've become more liberal with age, but being a millennial that's not saying much.
The difficulty is separating out the generational divide with actual change over someones lifetime. As an example when todays 60 year olds were growing up multiculturalism and internationalism were not as prevalent. Most people that age didn't grow up going to school with people from Poland, India, Africa etc, and as such may have more of an aversion to immigration due to that. Racism was more acceptable, where for the young today it's been drummed into us that it's bad. That's just one example of variability in just one of a myriad of issues that could be grouped under the question. Are people more "grumpy" as they get older, or does it just seem like that because the world moves on?
