This makes no sense at all. You've associated things that are simply not associated and filled your comment with non sequiturs. Our economy has boomed since the Reagan era tax reforms as well. There were tax reforms in the JFK administration too.
If you've a specific tax proposal make it, but your vague belief that there was something special about pre-Reagan tax structure is nonsensical. Tax rates were higher, but applied to less income. Do you have any idea what the practical differences were?
Tax foundation refutes your claims rather handily.
