It is now about $57,000 per person, and with just 2% inflation per year (1980s had around 10% per year on average).
Some possible ways that this presentation might fall short of making your case:
Average income does not actually tell us how the bulk of folks are doing. How about some other measures of central tendency such as the median, or a number for what the middle class income averages. We know that globalization has produces increases in wealth. What is questioned is who and how many folks have benefited.
Your inflation numbers as cited don't provide us with any meaningful way to compare current income to 1990s income, because you only provide current inflation while comparing todays income to income from over twenty years prior.
The immigrants have the highest incomes. Look at the average Indian American income.
