Your paying higher taxes contributes likely more to the community than another store.
Your paying a local charity usually does much more to the community than even running a gym.
If you run a store or a cafe by just paying locals to work in it, using a part of your high wages, it's pretty helpful. But see the charity above; maybe it's better to support e.g. educators.
In general, your community is never better off if you suddenly become poorer.
Using the money to pay others to start more local schools, maybe a free coding bootcamp (with entrance tests), maybe maybe could be a high impact thing to do?
Or a charity yes (unless of course it's sth like a SPA for dogs)
