Being able to travel often doesn’t have much to do with the tax bracket. Obviously it depends on where you’re travelling but I have a lot of acquaintances and friends that have been travelling around the globe in their early 20s.
Were they staying at Shangri La every single time? No, mostly hostels, airbnbs, friends.
The more you travel, the easier it is to keep travelling. You’ll meet people from all over the world and they will often invite you to sleep on their couch.
“Wow you are so fun, if you ever happen to be in Barcelona, my couch is available”
Like many things in life, if you lower your expectations, you’ll be able to do what you dream of.
