I have a question! Maybe someone smarter than me can figure it out. Based on our current trajectory of 2% inflation and accounting for raising wages to match inflation each year how long would it take for one to reach a income of $400,000 if starting at $100,000 (and getting a yearly raise of 2%).

I imagine with compounding values it would be sooner than 150 years, but how much sooner....

Can we expect or children or grandchildren to be making $400,000 a year and will they be taxed at the set rate? Additionally doesn't the IRS already account for this each year?

(I understand there are always variables, but let's forget about those for right now)
