Easy to do.
Put $1,000 in a stock lets say HRL Hormel Foods where I worked. If I would have done this in 1980 this would be the outcome
IRA $1,000 1980 dollars adjusted stock price in May 1980 $0.23* or 4347 share today. Today's value $36.40 a share. $158,260.00 ALL is taxable when you take it out. Say 20% or $31,652 in taxes you get to keep $126,607
Now Roth IRA same $1000 but you paid tax before you put it in the Roth IRA. So you are out an additional $200 if you are in a 20% bracket. Growth is the same and you still end up with the same $158,000 you get to keep it all without paying tax on it when you take it out after retirement.
The above growth numbers are real. I did buy $25.00 in HRL stock each week when I worked. Wish I would have put it in a ROTH IRA.

Many splits and lots of growth. I have not included the divided that is near 2% per year.
