(You meant "renouncing" but that is OK. Typos happen).
What you should also recognize is that if any state became a conservative independent nation, it would hopefully leave all the federal baggage and waste behind. If Texas went with a strictly conservative government (and actually banned Communism), it would do the following:
1. Reduce the income tax to a flat tax of 10% of gross income (personal or corporate) and keep tax filing simply. Just one page showing gross income and 10% tax.
2. Totally eliminate tax deductions and tax credits.
3. Maintain strictly balanced budgets, with no deficit spending, and no government borrowing.
4. Make a commitment to use tax funds strictly for essential government services and infrastructure. No pork, no subsidies, no wasteful expenditures.
5, Reduce government agencies, politicians, and bureaucracy to an absolute minimum, and focus on law enforcement.
6. Make free enterprise the bedrock of the economy, and not interfere with the private sector.
7. Leave retirement planning to the private sector.
8. Block all imports from China, or impose very heavy tariffs.
9. Encourage the manufacturing of all goods and products within Texas itself.
10. Make doing business with Mexico contingent upon no border violations, no drugs, no trafficking.
11. Eliminate the welfare state, the nanny state, homelessness, etc. Make able-bodied people work for a living.
12. Go back to the gold standard instead of fiat currency.
These are all common sense measures which all governments avoid. But if people pay less in taxes and retain more of their income (while well paying jobs are in abundant supply, and unemployment is minimal), they can actually put aside huge savings for retirement, or any other purpose.
