And to not be only critical, here's what my policy for growth and innovation would be:
1) Decrease the income gap between the rich and the poor. This isn't just about raising wages for the poor, but also decreasing wages (via taxes or maybe just straight up regulation). I'm not suggesting that we pay everyone the same: it should still be possible to become rich. But the current difference of ~4000x between a full-time minimum wage job and the top earners is obscene. Decreasing the income of the super rich will not really hurt them, and businesses would be better off reinvesting that money in making improving the business, or the whole country would be better off spending that money on social services. Increasing the wages of the poor and middle classes will help them immensely. Too many people live paycheck to paycheck, where a single illness can destroy their lives by forcing them into payday loans or credit card debt that becomes impossible to get out of. These debts are a drain on the economy, and forces a large portion of the US population into wage-slavery. Our goal should be to have no one living paycheck to paycheck, giving folks the ease of mind and comfort so they have an opportunity to innovate a=instead of just struggling to survive.
2) Increase the social safety net. This includes everything from improving and expanding government sponsored health care, to improving government sponsored retirement, to expanding government cash payments to individuals (either through welfare expansion or some sort of basic income). The theory behind this is that innovating (doing a startup) is giant risk most people aren't willing to take. And unless you're independently wealthy, it's a risk most people shouldn't take. Found a startup, get a cancer: you're bankrupt. Work for a startup that that doesn't have a retirement plan and doesn't pay market wages in hope of the IPO payoff, and they go bust: there goes a big portion of your retirement, hope you like working till you're 80. Increasing the safety net means people will be more willing to take risks, and some of those ricks will pay off, driving innovation and growing the economy.
