I mean, I think that's part of the responsibility of people who aren't being restricted economically. There are people living in massive expensive mansions within a few miles of people who live on the street or struggle to afford tiny apartments. The contribution from the people who are sitting on enough money to do basically whatever they want needs to offset that. If you've got a 6 figure income and the extent of your contribution is going to a protest or pushing for the idea of a general strike without actually making material contributions or logistical planning to make such a thing possible, that's not really going to cut it.
Just saying you want a more equal and just society when your own life helps to prop up the current status quo of massive wealth inequality isn't how we're going to get there. Doing something like offering cheap and well maintained rental properties for substantially less than their market value would go a lot further than taking 3 days off of work. Taking practical measures like directly sponsoring low-income families and providing them with things they can't afford would have a greater impact than walking around with a sign. Picking a random service worker and paying their rent for a month would have a greater impact than posting on social media. Seeking out homeless people and setting them up with housing with the weight of your financial ability would have a greater impact than passively wishing them well or giving them a couple of dollars.
Someone buying a new car and then going to a few protests a year or briefly excusing themselves from participation in the economy may make them feel good, but it doesn't undermine the systems of power that make it trivial for them to do things that would take actual sacrifice from the people who are already paying for the status quo with their labor and their suffering.
If your solution to injustice is to go ask the people who are disproportionately harmed by that injustice to be the ones doing the most legwork, your solution isn't a solution.
