Its hard to say because the value of money goes up with time. With Autotrader I can find a good car for less money than I would've had to spend 10 years ago just going to local dealers. Ten years ago I could find a more reliable car for less real money than 40 years ago.
Your salary will go up with inflation, but prices will go down in real terms. But at the same time new technology will come along that you feel you need. For example, if it currently takes you 40 minutes of work to get the money to afford a day's worth of food, in 2036 it'll probably only take 15 minutes a day worth of work. But by then we'll have alot more new stuff. Fifty years ago it was rare to have more than one TV and TVs were black & white 13". Now everyone has multiple color 20-60" TVs. At the same time in 1950 it may've taken 20 hours worth of work at an average salary to afford a 13" black & white TV (that is a guess) and now it is closer to 4 hours.
