I've already made this decision: When I become a multi-millionaire (yes, it can happen!! LOL) I am going to buy an island.
I will have 4 rules.
1. Don't take stuff that is not yours.
2. Don't hurt other people
3. Everyone is equal
4. If you don't like it: leave.
That is how I'd change a country. There are too many laws. Too much legal cross-talk, and too many attempts to control the masses.
make the rules clear, concise, and single-minded. If people understand what the rules are, they are better able to follow them.
Ever try to READ a Congressional law? You may as well read old English manuscripts, where they spell words differently depending on who is writing.
Changes I'd implement: Get rid of anything that is even questionably against the Constitution of that country. If there's any doubt, throw it out. Investigate those who likely abused their power, from the President, on down... Get rid of all benefits to other countries until our own country is fixed. Citizens of one country should not be held liable for the poor management of another country.
I guess that would be the first 100 days.
