People don't get more conservative as they age, they get more conservative as they own property and have children.

The opportunities have been squwished sway from most.

A valid point that's been delayed or even out of reach for my generation. I suspect you will see the trend moved back to a later age but if you notice it GenX didn't bounce the way Boomers did and some younger GenXers would have been in their 20s when 2008 hit.

Another issue is people are living longer. In the GOP especially primary voters tend to be older and want candidates who are less palatable to a general electorate. 

The issue is that this chart is Anglosphere centric and most Anglo countries have a first past the post winner take all electoral system leading to a two party system like the US or two party dominant system like the UK, Canada, Australia, NZ. This does not seem to be the case in multi-party systems given the victories the right has had in continental Europe.

What you have in the US is a Democratic Party that campaigns on handouts for young voters and a Republican Party establishment that wants to defend the established wealth of Boomers and the silent generation and the welfare state for elderly voters, zoning laws etc. but tell the young they have to pay for it but pull themselves up by their bootstraps. Who do you think they'll vote for?

I think woke social issues aren't as important as people think, social issues have usually been about stirring up the "foot soldiers" of each side. Most people are followers and will follow the social trends. If you look at history socially progressive views are the exception that crop up at various eras in history, not the norm.

A huge upcoming divide in a few decades is going to be when the Boomers start to die and pass on their wealth. A lot of this is tied up in home equity for Boomers who worked traditional middle class jobs but whose homes and 401ks outpaced inflation for years. I'm not talking big CEOs or even doctors and lawyers but average Boomers who lived at the best time and place for hourly wage earners in history and managed to have a stable enough personal life to build up some personal wealth.

There's going to be a huge divide as the suburban middle class leftist college kids of the 2000s-2020s start inheriting this money. People who come from poorer families or broken homes that have become prevalent since the 70s or whose parents who had major substance abuse problems and couldn't hold a steady job aren't going to benefit from this transfer of wealth.

Now these Boomers may not be wealthy enough to give their kids a trust fund or to have paid their full tuition now but they'll do well when they get their inheritance, a lot of them might be buying houses for the first time in their 40s and 50s and there's going to be resentment from the part of the population that didn't benefit from that. As for these newly flush Millennials they may start to say well my parents worked hard and were responsible, didn't do drugs etc. 

Even if their parents didn't come from poverty they will look back on tales of grandparents who pulled themselves up by the bootstraps in the Depression and didn't accept handouts. Even if their grandfather was a white male in a racist, sexist era he still grew up poorer in absolute terms than the modern poor etc. By that time they may have paid off their student loans after 20 years and yeah it was tough and yeah they campaigned for Bernie but in the end they got a job they didn't love and went to work and paid it off. Thus the modern campus leftist has transformed into tommorow's conservative.

This is going to lead to a massive divide in society and we will simply end up with the same dividing lines we had in the past only over different issues. The left will seek the votes of those who have not benefitted from this transfer of wealth. The right will adapt on certain issues as the older generation dies out. Culture wars will be less salient but there will be an intense divide over economics. Ironically the true trust fund baby leftists will be most likely to actually remain on the left because they can afford to pay more anyway but those who inherit moderate wealth will be the ones who move right.
