I guess it's the human condition that those who inherit riches or gain them- seek to conserve and pass on their riches to their own. In order do that they form alliances, feel comfortable among their own, build on their power and certain political parties form with those guiding principles. They seek party financial contributions from other rich people, to form a mutually beneficial, powerful, well financed, political alliance. They organise and congregate well, usually because their overarching goal is common- i.e. to always preserve and protect their riches, power and alliances. They do not seek equality as that would diminish their personal riches. They may electioneer that they're seeking to make their country great again (MAGA) but in reality it's always about conserving assets and building power and influence.
Yet they must win popular vote to win elections. Not many voters are rich That's why the choice of a charismatic populist leader becomes so important. A leader that appears strong will always appeal to those who feel left behind or let down financially or otherwise by incumbents. They may need to make manifesto promises to appeal to those whose votes they seek, who have very few riches, and will work out ways to do that, but when in office will always rule according to their mutual benefit and shared power and influence of course.
Those who have not inherited or gained riches, or even if they have, hold a set of values where they value equality, ie to distribute wealth for the benefit of all society, may seek to congregate differently to the historic political parties that are driven to conserve the stars quo/riches. But they are much more diverse, with many competing priorities, their overarching aims not so clear cut, have more differing views how to distribute wealth, don't organise so well and do not appear so strong.
They seek equality, they take more time to discuss to seek consensus, they change course, appear not so strong, are not so good at communicating their story. Shambolic on occasion- let's face it.
As individuals we will be attracted, unwittingly to strong leaders to feel safe, or we will consciously decide where we fit best, perhaps what serves us best, will consider what groups share our values and consider what will be the best, or good/fair enough outcome in a complex world.
Government in a turbulent world is complex and difficult. What we hoped for will not pan out easily or always as expected. We either manage our frustrations when our chosen party makes mistakes (and some mistakes or unforced errors will be huge, embarrassing, stupid, selfish or misguided) and stick with them, or we chop and change allegiance believing "no party/leader could be worse" than the current.
History tells us they can...and often will be.....
