Inter-generational gap and inequality

I believe most of you have already observed this increase of inter-generational gap in our world. It seems that putting the same effort as the older generation will simply not enough, and cannot be rewarded similarly as the older generation. Of course this is in a relative-poverty sense.

The reason is very simple,

1. There is diminishing return of gaining knowledge and putting effort, because companies become more and more mature. The market will become more stale and monopolistic.

2. Because we are in a more peaceful era, it is way easier to transfer larger amount of asset to one's children as heritage.

There is a positive reinforcement of inequality under capitalism, because rich people can buy more power using money, and use this power at their benefit to make more money. This is just a feature of capitalism that money will naturally concentrate.

Why the current system is designed in a way that Inter-generational gap exists? I would like to suggest the following reason: people that are not yet born do not have any voting right. Therefore, i think any political system will have the tendency to sacrifice long term goal for short-term benefit, and let the future generations to solve the problem of previous era.

So what is your opinion how to solve this problem? Please take into account all aspects including politics and feasibility.

My suggestions are the following:

I think we should levy tax by age group. The reason is that different era has different opportunities and challenges. My suggestion is that we can levy more tax (including asset tax) to the richer old, in order to fund some of the pension and healthcare benefits that we need to pay out for other old people.

It is my observation that when people are getting old, many of them tend to have less physical desire and instead have more desire for personal bond. Older people need more healthcare and other services. Therefore, i suggest a gradual change of social structure for people at different age. For young people, the tax should be low, freedom should be advocated, including capitalism lifestyle. But when you are getting old, more responsibility and tax will be levied, until the social structure becomes more socialism for the very old people.
