Money is a tool. You can use it to make yourself better able to safely plan or take part in actions. You can also use it to fund actions. Sometimes being a paypig for lefty projects is actually more useful than being an organizer in your spare time. It all depends on context.

Material conditions, e.g. pay for a job class, shape the likelihood of whether one becomes class conscious. They are not being class conscious in and of itself nor being on the right side of the fight. Making more money doesn't make you bourgeois, but even among the bourgeoisie there are class traitors that help our movement to the extent they can from their positions as exploiters. And there are plenty of lefties that are petite bourgeois, it's a very easy thing to be. And you'll still just be working class but simply making more money.

The only real risk is that you may be surrounded by a new set of PMC climber colleagues whose interests are entirely selfish and against our overall struggle. You'll want to be able to prevent yourself from being influenced by their nonsense. This requires political education on your part. If you feel insecure about your political education, it's never too late to start checking off items on your reading list! Similarly, just ensuring you are in properly radical spaces that aren't full of PMCs is helpful for not feeling like you're a complete oddball all the time and that yes the precariat exists, yes they're treated in a fucked up way, yes imperialism exists, yes its targets can articulate exactly how it forced them to move to the imperial core, etc etc.

At your new job, you'll want to have camouflage, at least at first. This is so you can get that cash and begin redirecting part of it to good organizing projects / similar things. You're like a left infiltrator of a new organization. If you ever want to drop some of the camouflage, you can do so, but you can never re-camouflage once you've done so in that workplace. Use this to your advantage. Have the backs of your coworkers that deal with the negatives of PMC ideologies. Be "cool" without revealing exactly how far left you are. Keep focus on individual issues, individual elements of working conditions in a calm and pleasant way. And then, if you ever want to do more and have a hard fight, you will be a trusted known commodity that's in a strong position to start forming a union.
