The existence of internet and technology as general terms, do not necessarily have to promote nor hinder excessive financial materialism in today’s world, contrary to what some or even most people may believe.
The internet, as a general term, is the biggest source of knowledge available everyone with access and connection to it. The nature of the internet, as such humanity’s grandest portal to data and wisdom, does not have to be specified to excessive materialism, nor is biased towards it, for even an ascetic can have access to the internet - and still remain ascetic.
The same goes for technology. Every device created by humanity is a part of technology, from the wooden hut to the new smartphone. Thus technology as a general term does not have to be, nor is, biased towards excessive materialism, for even before the industrial revolution and long before it, people were excessively materialistic.
Therefore, the internet and technology does not have to stop one on their quest to reduce financial materialism. The key to reducing it is moderation and satiation.
Once moderation is achieved, one’s habits that represent excessive materialism, slowly but gradually, decreases as a tendency within the individual; when we constantly moderate use and consumption, the body and mind begin to lose their strings to the device, person or action which we are addicted to, making ourselves more used to less and less of whatever thing is that we’re attached to. Gradual moderation is key to ultimate rehabilitation, until optimal if not full independence is acquired.
One can know that they’ve become more independent, or completely independent, from the source of addiction (for excessive materialism, AKA obsessive consumption and the emotional attachment to many products and consuming more of these - IS an addiction) - by acquiring satiation from moderated amounts of usage and consumption one finds sufficient and different from the original usage and consumption of addiction.
Think about food - you don’t really need to eat a lot to be satiated, but your stomach grows in relation to the amount of food you eat, making you hungrier than you should. The same may go for one’s brain - not much interaction with some things and beings are generally required, but interacting with said things and beings, beyond the level, the line, one should find satiation within it- is a potential recipe for long-term addiction.
Thus, to make oneself less hungry, one must eat less until their stomach is to be decreased in size - the same applies to the areas of the brain that are overstimulated, leading to the phenomenon of addiction. Even at the cost of negative feelings - decrease one’s consumption and usage, making one’s presence in the lower lines shall become a habit, until the feeling of satiation, where said presence is preserved once more.
A reduction of something that generates fun within our bodies, even if the fun ought to be consumed more and more times through addiction, is not preferable for a feeble mind at all, although it can make them healthier and stronger. The line between beneficial fun and destructive fun, is extremely blur. With the power of logic, self-discipline and asceticism, the line between the two can appear more visible, even if by a little bit. Consume as much as you wish, but beware of unnecessary slavery, AKA too much dependence, and you can both enjoy and develop yourself through modernity, and still be an optimally-independent being. Be alone while together, be free within potential slavery.
