First off, anyone who says they can unpack the impact of economic policies with any degree of precision is lying. It is hard to imagine a more complex system with a greater number of factors and conflicting inputs than economics. That said, your implication seems to be that higher taxes are a net benefit to society. Is that in fact your contention?
Rent seeking is never pretty.
For the most part, stop cutting taxes, balance the budget and determine what society wants as goods and services they want provided/managed by the government.
I can buy into some higher taxes are a net benefit to society, its the haves take care of the havenot. Not as in socialism, but as the haves give a little more to keep the havenots from committing violence against the havenots. I think some social welfare is cheaper than incarceration. Public schools keep the youths from running the streets during the day and hopes that they will aquire enough education to be functioning (and hopefully productive) members of society.
Also there is a lot of common good services that comes from taxes collected, you may not be directly affected by the service, but you probably still reap the benefits. One I can think of is state meat inspectors, they visit food processing places to insure the quality of the meat being produced is fit for human consumption. Another is the weights and measures folks who certify commercial scales are accurate.
I'm still mixed on corporate income taxes, for the most part I don't think entities should pay income taxes, because their payroll should be where the taxes are collected. Property taxes, yes. Sales taxes, yes. Fuel taxes, etc. That being said, I think all incentives and bonuses to people should be paid as money (and taxed as income) and not stock or deferred comp over the maximum annual 401k contribution.
If you are business owner and choose not to incorporate, that is your own fault, expected to be taxed as an employee.
I think all tax write offs should be taken away, pick a base income where there is no income taxes are collected, then a graduated level by income to whatever percentage for the top earners. Not a flat tax.
