While it is okay to live in reasonable comfort, many modern luxuries are a diversion from what is important.
More luxurious cars, nicer houses, expensive shoes or jewelry? Who needs that?
The only thing that counts is optimal sexual relationships. If one's sex life is optimal, it's all right to live in a bamboo hut and use public transport… or even just walk, even for many, many kilometers.
Many men spend money on luxuries, not because they enjoy them but because luxuries express status, and they want to express status because they want to attract attractive females. If being a homeless, begging monk would be the most effective way to attract women, then you would see a very large number of men switching to that lifestyle.
But if luxuries are an unneeded diversion, what should men who possess a lot of money spend it on?
Sooner or later, it will be political causes. Causes that benefit them directly, not just economically but, ultimately, sexually.
It is impossible for constructive processes to have such an effect. Only destructive causes are radical enough to change the modes by which humans live together so fundamentally that men with means, and brains, will have a far-reaching chance to benefit.
Possible causes include movements that fragment countries, especially the USA. More, and smaller, countries mean more options. Smaller countries also have less capacity to intervene in other countries. Any political independence movement in the Western world deserves support.
Other possible causes are movements that favor the liberalization of drugs. Drugs undermine conventional morals and value systems. Drug subcultures also undermine the common sexual discrimination against older people.
Possible minor causes include isolationist political agendas, any kind of multiculturalism (as it is a seed for fragmentation), and causes that ease worldwide migration. The mixing of populations has the potential to result in conflict; conflict is destructive, and opportunities follow destruction.
