There is a reason there is a profit. It is because someone has decided to undertake several risks:
1. They have employed someone who is a complete stranger, and they hope that they made the right choice by employing them. The risk here is that the employee will either not do the job they agreed to do or they will do something that costs the employer their reputation and/or business (which is their means of making a living).
2. They have decided to produce a good or offer a service, and they are taking a risk as to whether consumers will purchase that good or service. If the consumer purchases what they offer, then the profit they make is a reward for the risk they took.
Profit is a means for a person to make a living off their labour or by risking investment in the labour of others in the hope of being rewarded. Profit is also used as a means of reinvestment into the business so that it can grow and employ more people or produce more goods or services.
Your dislike of materialism is your preference, but not everyone shares your preference. Just so you know, property is an essential part of freedom. You do own yourself, right?
