from the internet:
First, tell your kids to open a lemonade stand. Watch as they make lemonade, paint a sign, and move a table and chairs and a pitcher and cups to your front lawn.

Then let them sell for a few minutes unimpeded. Then come along and tell them you're from the Department of Agriculture, and want to see where the calorie count for their products are posted. If there is no calorie count, take 25% of what they have earned as a fine.

Then leave them alone for a few minutes and come back and ask if they are aware that they are violating child labor laws. When they tell you they are unaware, take 25% of what they have remaining as a fine.

Then come back a few minutes later and ask for the environmental impact statement for their lemonade stand. When they ask what that is, explain that before stand can be allowed to open, you have to study whether the ants under their feet or the squirrels in the trees above them are discomfited by the lemonade stand. If you notice any ice cubes melting on the ground to form a little puddle, say that is wetlands and can be regulated by the EPA as well. Assess a 25% fine of what they have left.

Then come back a little while later and ask if they have been investing in healthcare for their employees, and withholding money for social security and Medicare. If they haven't, assess a 25% penalty.

Then come back a little while later and ask why there are no girls working there. Or if there are girls, ask why there are no blacks. Or if there are blacks, ask why no Hispanics. If there are Hispanics, ask why no gays. If there are gay kids, ask why no transgendered. Say that the absence of one group is evidence of discrimination, and assess a 25% fine.

Then leave them alone for a few minutes and set up a competing lemonade stand right next to them, with the sign "Luis Gutierrez Lemonade, 5 cents". When the kids ask what you are doing tell them you are an illegal alien come to this country to compete for their jobs. If they start crying tell them that crying about it is racist and they could be fined.

At the end of the day count how much they have earned remaining after all your fines and take 50% of it. When they ask why, say it is for federal, state, and sales taxes. Explain that it was not they who sold the lemonade, but the government, who made the roads and sidewalks by which people came to buy it, and that they, the small business owner, are the "rich", and need to pay their fair share.

After all this is said and done, ask your kids if they identify more with the producers of lemonade, or the government inspectors. Then you will have explained socialism to them.
