You could easily freeze government spending and start to grow out of the problem (if we had pro-growth policy makers) and eventually solve the problem.
We had pro-growth policies all decade and we had a net jobs loss on the whole.
The thing that is different now as opposed to 30 years ago when we did sweeping tax cuts was people actually invested in the real economy. Their investments paid people, bought and made materials.
Fast forward, and now money is really only made on paper. Instead of investing in real tangible things, the people who used to create jobs now find it more cost effective to hand their money over to a hedge fund who is just going to move money around as a way of creating wealth.
That is how we were able to see GDP expand by 30% in a decade we lost jobs on the aggregate. It's why banks don't make loans all that much anymore. There is far more money to be made prop trading their there is loaning people money.
We could cut the taxes to zero, but the money bypasses the real economy and heads right to all of the fancy financial innovations Wallstreet is always busy concocting.
Before 2000, there was no such thing as a "jobless" recovery. Now it is the norm. Nobody is interested in creating jobs, and it is not because of regulations. It is because you can make far more money with that same capital letting the MIT geniuses program your computer with some fancy algorithms that can make you more money than you ever would starting up a good old fashion bricks and mortar store where you actually work to make money.
It didn't used to be like that back in the day, which is why old prescriptions that used to work are futile in this era of technology and fast money.
